Lesson 1: The Basics
A triangle is a polygon with three sides, or angles, or whatever.
Lesson 2: The Angsty Angle

Lesson 3: The Sides of Debate
Is it the hypotenuse that's most important, or the legs? Do you side with the isosceles, the equilateral, or the scalene? The debate rages on, but we'll get to it all in time...
