Question

Two lines intersect to form the angles shown.

Answer 1

Answer:

Option B and C are the correct option.

Step-by-step explanation:

To solve this question we will go through each option given.

Option A. since ∠1 and angle = 100° are supplementary to each other.

∠1 + 100° = 180°

∠1 = 180 - 100

∠1 = 80° ≠ 100°   Incorrect option

Option B.

∠3 and angle = 100° are supplementary angles

∠3 + 100 = 180°

∠3 = 180 - 100

∠3 = 80°   Correct option

Option C.

∠3 and ∠1 are opposite angles

Therefore, ∠3 = ∠1    Correct option

Option D.

∠2 and angle = 100° are oppsite angles

Therefore, ∠2 = 100° ≠ 80°   Incorrect option

Option B and C are the correct option.
