Lines Points and Planes
Location with no size or shape
What is a point
Angle Measuring exactly 90 degrees
What is a Right Angle
Points that lie on the same line
What is Collinear
Angles that share the same measurement
What are Congruent Angles
If A, B and C are collinear and B is between A and C then AB plus BC equals AC

Angle measuring below 90 degrees
What is an Acute Angle
Points that lie on the same Plane
What is Coplanar
two angles that share a common side and vertex
What is an Adjacent angle
If ABD and DBC are Adjacent then ABD plus DBC equals ABC
What is Angle Addition Postulate

Angle Measuring exactly 180 degrees
What is a Straight Angle
Lines that will never meet
What is Parallel
Angles that add up to 180 degrees
What are Supplementary Angles
The formula used to find the midpoint between two endpoints
What is Midpoint Formula
A flat surface filled with points that extends in all directions indefinitely
What is a plane
