What is Midpoint?
A polygon in which at least one line that contains a side of the polygon contains a point in the interior of the polygon.
What is Concave Polygon?
A rule that is accepted without proof.
What is Postulate?
Two angles that share a common vertex and side but have no common interior points.
What is Adjacent Angles?
