Tricky Triangles

You're in luck... there are only three types of triangles! Yay!

Let's get down to business... and then I'll attach another awesome video at the end for your enjoyment :)

Scalene: no congruent sides (all sides are different)

Isosceles: at least two congruent sides

Equilateral: all three sides are congruent

Okay, maybe I lied... there are three more kinds of triangles! Oops! But it connects to the post about the types of angles so it's pretty easy.

ONE MORE THING: 

The sum of the measure of the interior angles of a triangle always equals 180°

For example:

This is an equilateral triangle, so each angle measures 60°.

60°+60°+60°=180°

This is a scalene triangle. Each angle measures differently.

60°+50°+70°=180°

TRY IT!

40°+70°=110°

180°-110°=70°

Therefore, this is an isosceles triangle.

And now the moment you've been waiting for... ;)

Okay, maybe it's not too exciting... but it helps, right?!

I honestly do recommend subscribing to Math Antics on YouTube :) He has many more math topics he covers!
