Classifying Triangles
Просмотров 8Месяц назад
Congruence: Scalene: 0 congruent sides/angles Isosceles: 2 congruent sides/angles Equilateral: 3 congruent sides/angles Angles: Acute: 3 acute angles (less than 90) Right: 1 right angle (90) and 2 acute angles Obtuse: 1 obtuse angle (more than 90) and 2 acute angles
Complex Triangle Problems
Просмотров 20Месяц назад
Look for Linear Pairs! Look for Angles of a Triangle! If two sides are congruent, mark the two angles opposite them congruent If an angle is bisected, it is cut into two congruent halves An equilateral triangle has angles 60, 60, 60
Corresponding Sides and Angles in a Triangle
Просмотров 7Месяц назад
The largest side is opposite the largest angle The middle side is opposite the middle angles The smallest side is opposite the smallest angle
Exterior Angle Theorem
Просмотров 7Месяц назад
In a triangle, an exterior angles is equal to the sum of the two non-adjacent interior angles
Intersecting Medians (Centroid Problems)
Просмотров 5Месяц назад
Intersecting medians are cut in a ratio of 2:1. If given the small piece, multiply it by 2 for the large piece If given the large piece, divide it by 2 for the small piece If given the whole median, 2x 1x = median OR divide the median by 3 for the small piece
Isosceles Triangles, Angle Bisectors, and Equilateral Triangles
Просмотров 30Месяц назад
Isosceles Triangles: If two sides are congruent, the angles opposite them are congruent Angle Bisector: An angle bisector cuts an angle into two congruent halves Equilateral Triangle: The angles of any equilateral triangle are 60, 60, 60
Parallel Lines with Algebra
Просмотров 2Месяц назад
Same or Different? If the angles are the same (both acute or both obtuse): set the expressions equal to each other If the angles are different (one acute and one obtuse): add the expressions to equal 180 Substitute in if necessary
Parallel Lines with Triangles

FOLLOW THE TRANSVERSAL Look for linear pairs, angles of a triangle If two sides are congruent, mark the sides AND the angles opposite from them
Parallel Lines Cut By a Transversal
Просмотров 8Месяц назад
When parallel lines are cut by a transversal: All of the acute angles are the same All of the acute angles are the same Any acute and any obtuse angle add to equal 180 Extend your parallel lines Extend and FOLLOW THE TRANSVERSAL
Triangle Inequality Theorem
Просмотров 16Месяц назад
The two smallest sides of a triangle must add to be larger than the third side If given two sides of a triangle, to find the range of possible values for the third side: difference is less than x is less than the sum

🔥🔥🔥🔥🔥🔥🔥🔥😊
whats an i
This is an Algebra II lesson. If you’re preparing for the Algebra I Regents, you are not going to have to worry about i.
Your answer to #6 is not strictly correct. You need absolute value bars on the variable x outside the radical. Both x and z might be negative in the original expression, but the square root of the square of a negative number, by definition, is positive.
thank you!!
Volume of paraboloid. I hope you enjoy and share this knowledge on with others: ruclips.net/video/1Z_Bsmax8cM/видео.html

Thanks!
My favorite song ! 😭
fraaaancia!!
I can’t believe that you actually wrote new songs! Miss you! You’re one of the best teachers I had ! I’m still singing your songs
Not bad
bacon egg and cheese
well here we go again
Best math teacher ever. We need more teachers who care as much as you do. Shout out to the only math teacher who managed the worst math student ever to pass The algebra regents with an 85 when I was a freshman. I think it was the first year you taught. We called you guitar man. ❤️❤️✨✨
Thank you! But I don't recall ever having an Alice in class, I got horrible Regents results my first year teaching because I had no idea what I was doing, and guitar man doesn't ring a bell! Or maybe I'm just getting old and losing my memory! Thank you for the comment :)
Math Schlansky oh it’s Yajaira. Ha ha. I don’t think you would remember me. & That’s what we called you. Any teacher that helped me pass math one and never again deserves a huge prize. I aspire to be a teacher who cared as much as you one day. I still remember all the songs. Lol
Yes! Period 3 I think? My first year in Westbury. I remember all of my 80+! I'm glad I was able to help you!
Your songs keep evolving👌 this is great
Wait what happend to "clean it up for meee" it doesn't feel the same
Best math teacher I’ve ever had 🙌🏾
Oui, J’mapelle PotatoPorkSalad
Miss you dawg. This was truly a bop
All good things must come to an end
This wil definitely help my daughter pass
ur rly bad at explaining things
Haters gonna hate!!!
Math Schlansky lol I was kidding if u didn’t notice 😂 but now that I have read it, it doesn’t have my sarcastic flair😂 sorry about that
Did you know schlansky is a human being? You learn something new everyday
Yo, I thought he was a bacon egg and cheese the entire time
Question #1 The last choice has 4 zeros not three.
Correct! So does choice 2. I gotta watch out for those double roots!
Mr Rhodes call extension 5047
Schalansky 😐
Francia! You're looking at the wrong test!
Divide the rate by 100 yo!
FRANcia
Keep up the good work man, proud of u

Hi, would you have these questions in a pdf/doc format?
how do u do the third one by hand?
why do u have to add the 9 on the second question?
hey mr. its ambar from two years ago. I need help with matrix multiplication
Can I get the chords to Factoring and Sets from 2013?
And CPCTC
Lmao
Who failed...like
Can't wait to here this song next year
Imma wing it
Multiple choice was pretty easy. Half of the short response fucked me right in the anus.
SlothGiraffe how am I supposed to find the radius of a deflated volleyball given the volume. LIKE FUCK
Right? I got 0.33 or something, what about you?
SlothGiraffe I didn't even answer it. What did you get on the last question about how fast the plane was going?
Bro, I took a look at the last one and I just gave up. I know when my fate is sealed. The SOH CAH TOA shit is so confusing.
yo u need to chill out with that board
Good luck tomorrow everyone
me too. Are you ready?
this about to smoke me lmao
Got my regents tm and idk shit hopefully this helps
For question 19 it says least so wouldn't it be choice one
Tibble M no, if you only bought 1 bucket of paint you would have only been able to paint around half of the cube, the question is asking what is the least you buy while being able to paint the whole cube.
ContentZip ohhh I feel really stupid now
I Can't lie but this actually help me a lot tho 👌
I don't know you, but I love you and thank you for this finna fail my Regents tomorrow
Do geometry please
THANK YOU SOOOO MUCH!!!!! My geometry exam is tomorrow and I felt sooooooo unprepared but your video really helped a lot. You were straight to the point with how to solve a problem and it just was overall a great video so thank you again!
Brianna Renee same lol
You can use Pythagorean theorem for question 3... so yea, “good luck” to me I guess...
I’m a freshman and find geometry easy. Algebra on the other hand...
JigglyJuke same, I'm a freshman but failed algebra in 8th, but I find geometry easy except for proofs.
That time of the year... bout to kill myself. Definitely failing tomorrow
Mike Farina same 😂
It's L Szn
Mike Farina Same
you write so hard omg
I'm very passionate about geometry!
