​Congruent: same size, shape and measure

​

​

​

​

​

​

​

Endpoints: points where a line segments ends

​

​Ray- A line that starts at a point and extends infinitely

​Vertex: the point of an angle where the two rays meet

​Plane: A flat surface (Think of the plains out west. They're flat)

​Acute: Angle between 0 and 90 degrees

​Supplementary Angles: The sum of two angles is 180 degrees

​Line: An infinite length of points

​Obtuse- Angle between 90 and 180 degrees

​113 degrees

​

​Perpendicular: when two lines intersect at 90 degree angles
