**9) In the figure below, which of the following are corresponding angle pairs:**

a. ∠p and ∠q

b. ∠p and ∠w

c. ∠p and ∠x

d. ∠p and ∠z

Answer:** b**

**10) If AB || CD, EF ⊥ CD and ∠GED = 135° as per the figure given below. **

**The value of ∠AGE is:**

a. 120°

b. 140°

c. 90°

d. 135°

Answer:** d**

Explanation: Since AB || CD and GE is a transversal.

Given, ∠GED = 135°

Hence, ∠GED = ∠AGE = 126° (Alternate interior angles)
