Types of Triangles in Euclidean Geometry
HTML-код
- Опубликовано: 30 сен 2024
- If a shape is made of straight line segments, the minimum number of sides it can have is three. And three sides make a triangle! I'm sure you knew that. But do you know all the types of triangles? Oh you do? Then what's a scalene triangle? Hah! I knew you were bluffing. You'd better watch this right away.

Sir your teaching method is really very praise worthy. Sir upload more videos related to advance parts of geometry. Thanks sir.
I'm taking geometry over the summer right now so I dont need to take it during the school year and these things carry lmao
You've been with me ever since highschool man, Love ur vids!!!!
The two triangles at around 3:40 look to me as if the top and the bottom lines were parallel, which then would cause the bottom left angle to resolve to 70° instead of 60° (from alternate interior angles theorem).
Either I can't see it properly, I am missing something or the drawing is a bit unfortunate.
Anyways thanks a lot for these fantastic lessons!
3:40
I think you are correct Joscha. The upper line segment cannot be parallel to the lower line given these angles. I hope professor Dave will acknowledge this. Everyone can make such a mistake of course and it does not diminish the achievements of this series.
Yeah I checked the comments as I thought the same. It’s not defined they’re parallel maybe?
I think the problem is with the given it should be 150, not 140 degrees for the question to be correct. Nevertheless, it's still a great video

There was no claim that the lines were parallel, and they don't need to be.
2:41 i wish i was high on potnuse haha okbye.
LOL
What age group do you target your videos towards? Depends on the subject?
This material was taught in the 6th grade to me. Then pre-algebra in 7th. And algebra again in 8th.
they are targeted at whoever needs this information. with mathematics, i wanted to do literally all of the maths, so i started with arithmetic, and i will go all the way through at least differential equations, so everyone will get what they need.
@@ProfessorDaveExplains you are fucking awesome dude. I know pretty much most of the topics you've covered but im reinforcing my base level of knowledge and improving upon it and your videos were extremely helpful to say the least!
@ProfessorDaveExplains this is very architectural informative and very hierarchy way to let ur audience learning what they need, thanks dave. You manage them so well.
After my OCD obsession with the problem and using an online protractor after screen shoot the problem and measuring the angles the problem is with the small triangle the angles should be 40 instead of 30 and 60 instead of 70. You can solve the problem in any way you want using the alternating angle or the way that professor David explains it.
"figure not necessarily drawn to scale"
ISNT IT 70 and 30 degrees below too, in 3:40?
Yeah exactly. That what I was also thinking about
You are guessing that the lines are parallel but in this example Dave didn't intend to do so . So, actually the drawing is a bit off.
Just because lines appear to be parallel, doesn't mean they are. You can't make that assumption here. It is also not necessary. It doesn't matter if the lines are parallel or not, the solution works the same way.
Hah.. but they both is not have the same magnitute and not congruence. It's just similar.
Because of Vertical angles one must be 80° so , if it didn't mentioned the vertical angle it could have been other numbers
Yup I am in 6th grade and u may think this grade is easy but no honey. It isn’t.
Yes it is. You can learn all there is to know about it in a day.
@@Stoirelius that's unpossible.
Thank you so much it helps so I know that on the grade 5 work I know I am going to get everything right.
🤗
Great videos!
Update more videos fastly please sir
