Types of Angles & Their Relationships

Vertical Angles • Vertical angles are pairs of opposite angles formed by two intersecting lines. They are congruent. 1 4 2 3

Adjacent Angles Adjacent angles have a common ray. They are NEXT to each other 1 2 4 3 To get from one adjacent angle to another, jump over a side

Supplementary Angles Two supplementary angles form a 180° angle. The measures of two supplementary angles have a sum of 180° 1 These angles are supplements and adjacent. 4 2 3 These are supplements Their measures add to 180° 50 130 130 + 50 = 180

Complementary Angles • Two complementary angles form a 90° angle. are adjacent and complementary 6 5 15 75 These angles are complementary Their measures have a sum of 90° 15 + 75 = 90
