Shape Up
Triangle Definitions

 

 So let's take some line segments 

 and build shapes out of them.
 
 The most simple shape we can build is a triangle.
 

 

 
 The triangle is made of 3 line segments 
 joined end to end
 No matter what any triangle looks like exactly,
 one thing is always true.
 
 The three angles on the inside of a triangle
 ALWAYS add up to 180 degrees.
