Question

The intersection of parallel lines b and c and transversal line d form several special angle relationships, as shown in the image below.



If ∠1 measures 135°, what is the measure of ∠8?

45°
65°
67.5°
135°

Answer 1

Angle 1 and angle 5 will be equal because they both are corresponding angles.

Hence angle 5 = 135 degrees

Now, angle 8 is also equal to angle 5 because they both are opposite angles.

Hence angle 8 = 135 degrees : Answer 135

Hope it will help :)
