ANGLE NEXT An angle is formed by 2 rays or 2 line segments that share the same endpoint. The endpoint where the rays or segments meet is called the vertex of the angle. The rays or segments are called the sides of the angle. Table of Contents More info here!

Naming Angles NEXT The vertex of the angle must always be in the middle of the, between the points on the sides. A B C This angle is called: ABC The vertex point is B. That is why B is in the middle of the sides A and C. CBA or Table of Contents BACK
