Adjacent angles
Angles that lie in the same plane and share a vertex and a common side. They have no common interior points.
Alternate exterior angles
Angles that are on opposite sides of the transversal and lie on the exterior of the two lines that the transversal intersects.
Alternate interior angles
Angles that are on opposite sides of the transversal and lie with in the interior of the two lines that the transversal intersects
Complementary angles
Two angles whose sum is 90 degrees
Corresponding angles
Angles in the same relative position with respect to the transversal and the intersecting lines
Equidistant
The same distance from a reference point
Exterior angles
Angles that lie outside a pair of parallel lines
Interior angles
Angles that lie between a pair of parallel lines
Linear pair
A pair of adjacent angles whose non-shared sides form a straight angle
Nonadjacent angles
Angles that have no common vertex or common side or have shared interior points
Perpendicular bisector
A line that intersects a segment at its midpoint at a right angle
Perpendicular lines
Two lines intersect at a right angle. The lines form four adjacent and congruent right angles
Plane
A flat two dimensional figure without depth that has at least three noncollinear points and extends infinitely in all directions
Postulate
A true statement that does not require a proof
Proof
A set of justified statements organized to form a convincing argument that a given statement is true
Right angle
An angles measuring 90 degrees
Same-side interior angles
Angles that lie on the same side of the transversal and are in between the lines that the transversal intersects; sometimes called consecutive interior angles
Straight angle
An angle with rays in opposite directions; i. e., A straight line
Supplementary angles
Two angles whose sum is 180 degrees
Transversal
A line that intersects a system of two or more lines
Vertical angles
Nonadjacent angles formed by two pairs of opposite rays
