Answer:
Hint: Use the Angle Addition Theorem and the fact that a line is made up of two opposite rays. Given: m∠1 = 62° and lines t and l intersect
Step-by-step explanation:
Step-by-step explanation:
Given: m∠1 = 62° and lines t and l intersect
Prove: m∠4 = 62°
Proof:
Statement                     Reason
m∠1 = 62°                     Given
m∠1 , m∠2 are supplementary    t is a straight line hence linear pair.
m∠4 , m∠2 are supplementary    r is a straight line hence linear pair.
Angle 2=180-62 = 118 Â Â Â Â Â Â Â Â Â Â Â Definition of supplementary angles
Angle 4 = 180-118 =62 Â Â Â Â Â Â Â Â Â Â -do-
Angle 1 = Angle 4 Â Â Â Â Â Â Â Â Â Â Â Â Â Â Equality property
Hence proved
