Question

What is the measure of a in the figures if the transversal cuts the pair of parallel lines at right angles?​

Answer 1

Answer:

a = 90 degree

Step-by-step explanation:

because qor = por

so por = 90 degree

it is a straight line = 180 degree

so 180 - 90 = 90 degree

Answer 2

Answer:

A.x//y,w is a transversal a=90(corresponding angle

B.P//q,r is a transversal a= 90

transversal intersect p and q
