Review the Special Angle Pairs Below:

* Complementary & Supplementary Angles may or may not be adjacent

Linear Pairs: 2 angles form a linear pair if they are adjacent and they form a straight line

Linear Pair Postulate: If 2 angles are a linear pair, then they are supplementary

The measures of the two smaller adjacent angles add up to the largest angle measure.

Perpendicular Lines

Two lines are perpendicular if and only if they intersect to form one right angle.
