Chapter 1.5 Angle Relationships

Example 1 Identify Angle Pairs A. ROADWAYS Name an angle pair that satisfies the condition two angles that form a linear pair. A linear pair is a pair of adjacent angles whose noncommon sides are opposite rays. Sample Answers:  PIQ and  QIS,  PIT and  TIS,  QIU and  UIT

Example 1 Identify Angle Pairs B. ROADWAYS Name an angle pair that satisfies the condition two acute vertical angles. Sample Answers:  PIU and  RIS,  PIQ and  TIS,  QIR and  TIU

Example 1a A.  CAD and  DAE B.  FAE and  FAN C.  CAB and  NAB D.  BAD and  DAC A. Name two adjacent angles whose sum is less than 90.

Example 1b A.  BAN and  EAD B.  BAD and  BAN C.  BAC and  CAE D.  FAN and  DAC B. Name two acute vertical angles.

Angle Measure ALGEBRA Find the measures of two supplementary angles if the measure of one angle is 6 less than five times the measure of the other angle. UnderstandThe problem relates the measures of two supplementary angles. You know that the sum of the measures of supplementary angles is 180. PlanDraw two figures to represent the angles.

A.1°, 1° B.21°, 111° C.16°, 74° D.14°, 76° ALGEBRA Find the measures of two complementary angles if one angle measures six degrees less than five times the measure of the other.
