30 - 60 - 90 Triangles: GRE / GMAT Geometry
HTML-код
- Опубликовано: 27 авг 2024
- Everyone's favourite! 30:60:90 triangles are understood properly by very few students, I can almost guarantee you will learn something from this video if you are studying for the GRE or GMAT (or other exam this topic comes up in) and watch to the end. Triangle ratios come up occasionally in these tests but you can give yourself a big edge by understanding them!

The GRE and GMAT are two of most used graduate exams for those seeking to study a Masters Degree or Masters in Business Administration (MBA) degree. The Graduate Record Exam and Graduate Management Admissions Test have been taken for over 50 years and are taken by approximately 600,000 and 300,000 people worldwide annually, respectively. These exams are typically taken between the ages of 18-40, by those who have completed, or are about to complete, their Bachelors Degree.

She was admitted into Harvard Business School, The Wharton School of Business, and Columbia Business School (accepted into every school she interviewed for) after graduating from UCLA with a degree in Communication. She also got 3 perfect scores on the GRE’s Analytical Writing Assessment (99th percentile).

the first thing i do in the morning and the last thing in the night is watching your videos.. i have watched multiple other videos but nothing like the way you explain.. best content for gre on RUclips!! Thank you
That's lovely to hear Roopa :)
Hi Philip
I'm really not one to comment on social media but you really deserve a shoutout! My GMAT is in under 10 days and I haven't been able to dedicate the time to study as much as I hoped with a very hectic job! I was panicking about how far behind I am but your videos give me a reassuring sense of calmness and confidence. Thanks much!
You're amazing! Would love more videos on parallelograms, trapezoids and 3D figures, - geometry! ❤️ Love from India
You caught me! But I won’t hang my head in shame 😂😂😂 Thanks for these tricks, Phillip.
This is the best explanation for the special triangle. Thanks a lot tested tutor.
You are so amazing.
Your teaching method really helps to crack problems in few steps.
Wow! Thank you so much. I was so confused before this.
1000th like by me, thank u philip 🥰🤘🏻
Great tip : Just because it looks like a right triangle, doesn't mean it is!! Fallen for it many times. Gotta peruse the question and be vigilant. Your videos, as always, are edifying and repleted with cornucopia of virtuosity.
Haha thanks ab!
^ someone is ready for the verbal portion.
let us know your verbal score :D @abbhijith
Thank you so so so much. When i watch other videos i sometimes have to watch them a couple times to understand the concepts, but you explain so simply and eloquently that I understand mostly everything on the first go! Wow, also I'm so mad they never taught this box trick while i was in school haha !
Ty!!
So helpful, thank you for your work!
your videos provide so much clarity, I love them! Thank you for making difficult concepts easy to understand!
You're so welcome pooja!
Thank you Phillip! Clear explanations with great example questions :)
Thank you Coach. You are the best.
I love thiisss soo much!!!! I understand your explanation better than how the magoosh tutor explains it. YOU ARE THE BESSTTT!
Wow, thank you Jerrica!
Thank you The Tested Tutor for these simple quant hacks. Saves me so much time. Much appreciated!
Glad to help Alex. Good luck.
thank you for being so kind as you teach us
Haha, thank you Lika :)
Really love your videos, and thanks for infusing some humor. You caught me on that 3rd example without the right angle
Bro your tricks are lit 🔥♥️
So perfectly explained! Thankyou so much!
I have learnt so much quicker through you videos. Please make a video on finding missing lengths in similar triangles (3 triangles also). Since these type of questions seems pretty time consuming. Thank you!!!
Great idea! Will do
Sir, your videos are so much helpful for my GRE preparation. I have been loved with the ways you explain the concepts and examples. You are an awesome tutor I have ever seen. Can you please make video on 45-45-90 degree triangle? Hope you will upload more videos on GRE. Love from Bangladesh.
Thank you 🤝🤝🤝
You caught me 😂. I even paused and worked it out only to press play and I am ashamed of myself
Hey Phillip, I came across a similar question as the last one in one of the practice tests and instead of giving us an angle, it was given that CB is equal to the radius of the circle, I got that question wrong as I didnt know what to do. Thanks for your trick.
Thanks
I really wish you’d make a list of short hand math. As an engineer grad, I know these maths skills, but they’ll just take me a while. It’ll prolly be too late for me, but for others.
Thank u philip❤️❤️
You are the best !
Thanks Lolu! Look out for your name in my video today!
Another useful topic!!!so great to learn from you sir💯💯
Glad to hear that Silkina
Thank you so much
@ 13:39 example , maybe this is overthinking but I thought to use pythagorean theorem to find find line AC which will correspond with angel ABC then form an algebraic equation based on the values of the side we are given .i.e 90 degrees corresponds with 16 therefore ac can be found by forming an equation that "matches " the two . Totally different angles but they add up to 180 ?
Great teacher ; Can you explain a bit the rule applied in last question where you called it right angle
Lovely video man =). Hats off.
Super helpful! Please do a video on other shapes like cubes, cylinder etc. Much love from Bangladesh!
Noted!
A lot of love for you
Hi thanks for these amazing videos, but i have a doudt , the dout is , So the base is basically wbere the 90°angle lies in 30 60 90 triangle.?
Very informative.
Thanks Rekha
The trick question actually tricked me and I perceived it a right angle 😮😅
I've watched your entire quant playlist, does this cover everything I'll need for GRE?
Nope! Much more to tell. Try to finish the Manhattan 5lb guide...
Great thank you very much
Welcome 😊
Love it! Very well done.
Thank you! Cheers!
I feel like i was in high school 19 yrs ago, only with a better version of my high school math teacher.
For the "bring it all together question", I still do not understand how you know which side is the hypotenuse. If when looking at figures on the GRE you should know things may not be drawn to scale, how do you know whether the diameter with center O is either the hypotenuse or larger side?
is the angle opposite to the diameter with the center on it always the 90 degree angle?
Diameter must be longest side
@@colleenmadden11 probably too late but could help someone. The angle inscribed in a semi-circle is always a right angle. So in this case, angle ACB is by default 90°.
Hi.... how do we determine which side is the height in the last example (17: 50)?
Any perpendicular side actually
But if it would have had a right angle I would have gotten it right! 😎🤣 Thanks!
Hi Philip, do you have a specific video on roots/square roots? I couldn't find it on your channel
Not yet, but want to get to it asap
Hey Phillip! In the question @6:31 if we write x√3=12 and then x√3=2√3 it gives x=2 which changes every side of the triangle. is there something wrong with this approach? please help..
Hi! Can u tell the best books to prepare for GRE? Couldn't find on your channel...
Manhattan 5lb guide and powerprep online tests
Hey Philip, I scored 303 a few months ago with 143 in verbal. ? What can I do to boost 10 marks..how much should I practise?
My exam is in another 40 days
Watch every video is a great start!

im confused but thanks
I've finished the Manhattan 5lb guide with 10% error while solving the questions. Will you please suggest me what's next to score high!!
Do every Powerprep test!
@@TheTestedTutor Alright sir🙌🏾
@@TheTestedTutor how about ranra and Watson critical reasoning. Do you have a video?
Yes you caught me lel
Your comment ‘hang your head in shame’ was very rude.
Lol
Isn't this basic trignometry?
this is just trig lol
