1-5 Angle Relationships
• Adjacent Angles: two angles that lie in the same plane, have a common vertex, and a common side, but no common interior points• Vertical Angles: 2 nonadjacent angles formed by two intersecting lines.• Linear Pair: pair of adjacent angles whose noncommon sides are opposite rays.
• Complementary angles: two angles whose measures have a sum of 90o.
• Supplementary angles: two angles whose measures have a sum of 180o
Perpendicular Lines: lines form right angles
