vertex The point where two consecutive sides of a polygon meet.
diagonal A line segment that connects two vertices of a polygon and is not a side.
Other terms
circle A set of points at a fixed distance (radius) from a point (center).
parallel lines Two straight lines on a two-dimensional plane that do not intersect no matter how far
they are extended.
perpendicular lines Two lines on a flat surface which make a right angle when they meet.
line segment The part of a line between two points.
ray Part of a line that starts at a point on the line and contains all the points on the line that
are on one side of the starting point.
base A special side of a polygon used to compute area.
(See examples in problems MP-16, MP-43, and MP-55).
