Question

What is special about exterior alternate angles when two parallel lines are cut by a transversal ?

( 1 )
A) Exterior alternate angles are equal

B) Exterior alternate angles are not equal

C)Sum of exterior alternate angles are 180

Answer 1

ANSWER: The measures are equal. Alternate exterior angles are "exterior" (outside the parallel lines), and they "alternate" sides of the transversal. Notice that, like the alternate interior angles, these angles are not adjacent. ... If two parallel lines are cut by a transversal, the alternate exterior angles are congruent.
