Triangles - Basic Introduction, Geometry
This geometry video provides a basic introduction into triangles. It explains how to calculate the measure of an interior angle of a triangle as well as the exterior angle. The sum of all three interior angles is 180. The exterior angle is the sum of the two remote interior angles according to the exterior angle theorem. In addition, this video explains how to calculate the length of the midsegment of a triangle. It contains plenty of examples and practice problems.

Thank you for teaching me what my teacher would teach me in one semester within one 23 minute lesson. This channel is literally the best with teaching math in general. I've learned so much from this channel and it's just amazing how much it helps.
let's take sometime to appreciate this wonderful teacher who gets straight to the point he taught me algebra,long division,intergers and ext . respect
MR. Organic Chemistry Tutor, thank for another incredible video on the introduction to Triangles in classical/modern Geometry.

Ok so I need help for this problem. My paper says “find the value of each variable” it is an isosceles triangle. Length C and A are equivalent. Length C is (9x -25) length b, the top, is 104. How would I solve this?????
Idk how much I can thank you but that really helped I’m understanding even more just watching and listening

I'm looking forward to taking the isee, however, I never was taught geometry at school, and the little I was taught, didnt learn because I didnt care about school until 3 months ago, so im re-learning algebra 1 and learning geometry, im currently taking algebra 2 and looking forward to taught myself pre calc and calc before my school even gives me those subjects, hopefully I do well on the exam!
Day 157 of my teacher not explaining things be like:
Sir, I don't understand the following:
Hello! My quiz is tomorrow and all I did was just procrastinate but your video helped to keep on track again, but still I hate math

where did u get the 180 from

How did you do 180? 0:27
Hey dude. In Turkey, even the lowest level student can understand this explanation. Turkey's education system is very difficult, we saw these questions in the 5th grade, I think they are given in high school too. Ah, if only our subjects were this easy.

A legend
16:33 stop right there. FEBD is a quadrilateral with two angles known (90 degrees defined by the altitude), one already calculated (from the larger triangle) and only one unknown, which turns out to be 110 degrees. This is equal to its opposite angle F at the crossing point of the altitudes.
In problem no 9 vertivke angles are congruent. Why by mid point
how did you get the 180 in 17:17 i dont get it its a right angle but you said its 180

At 12:30 where you solve z, why don't you just imagine it as if they're a whole triangle? (180-30-90=z) instead of using that formula?

2 is multiplied to both sides to cancel the fraction 1/2. DF remains on the right hand side while on the left hand side, HK is multiplied to 2 so the equation will be DF = 2HK (hope this helps)

For the first question in the example you can just do 180 - 70 - 60 to get X = 50 rather than doing it in a confusing way
