Angles:
An angle is either the figure formed by two rays starting from a common point or the
measure of such a figure.
Complimentary angles are two angles whose sum is  .
Supplementary angles are two angles whose sum is  .
Congruent angles are angles with the same angle measurement.
Vertical angles are angles at an intersection of two lines that are not adjacent to each other.
Interior angles are two angles that are in the interior of a polygon.
Exterior angles are two angles formed by the side of a polygon and an adjacent extends side or two angles on the outside of two parallel lines.
Pythagorean Theorem:
The Pythagorean Theorem is the sum of the squares for the legs of a right triangle equals the square of the hypotenuse, or .
30-60-90 Right Triangles:
The sides of 30-60-90 right triangles are in the ratios of  .
45-45-90 Right Triangles:
The sides of 45-45-90 right triangles are in the ratios of  .
Regular polygon:
A regular polygon is a geometric figure with three or more sides in which all interior angles are congruent.
Area:
Area is the size of a planar region or surface of a solid.
Volume:
Volume is the amount of space taken up by or enclosed by an object.
