A acute angle has three acute angles
A right angle has one 90 angle
An obtuse angle has one obtuse angle
If the sum of the measures of two angles are 180, angles are supplementary
Are formed by two intersecting lines and are opposite of eachother
They share a vertex and a side but no points interiors
Rays
A ray is a part of a line. That it has exactly one endpoint
