0:00 right triangles
0:24 acute & obtuse
1:01 equilateral
1:30 isosceles
2:24 scalene
2:35 what kind of triangle?
3:21 (Greater Gator’s Class) pythagorean theorem

One of the most powerful shapes… The triangle!

⚠️⚠️ Remember! The sum of the (interior) angles of a triangle must always be 180 degrees! ⚠️⚠️

What does it mean for a triangle to have an obtuse angle? What does it mean if a triangle is equilateral or isosceles? I see a lot of other math teachers splitting this up into multiple lessons. You’re going to get one crash course, so that by the time this video is over, you can identify any triangle anyplace, anytime. To be able to pinpoint an isosceles triangle with laser precision? Definitely one of life’s most important skills. How important? Just watch…
