These angles measure more than 90 degrees but less than 180 degrees

Two adjacent angles that form a straight line and are supplementary 1 2

An angle that measures exactly 90 degrees

These angles are on the same side of the transversal and located in the same position. They are equal in measure 1 2

These lines have slopes that are Opposite reciprocals of each other. The product of the slopes is always -1.

Used to find the sum of the interior angles of a polygon

These angles are on opposite sides of the transversal outside the parallel lines. They are equal in measure. 1 2
