Question

∠r and ∠s are vertically opposite angles of each other . Measure of ∠r is 80° then find measure of ∠s.​

Answer 1

SOLUTION

GIVEN

• ∠r and ∠s are vertically opposite angles of each other .

• Measure of ∠r is 80°

TO DETERMINE

The measure of ∠s.

EVALUATION

Here it is given that ∠r and ∠s are vertically opposite angles of each other

Measure of ∠r is 80°

We know that when two lines intersect Vertical angles are pair angles formed

Again Vertically opposite angles are always equal.

So we have

∠r = ∠s

⇒ ∠s = ∠r = 80°

FINAL ANSWER

The measure of ∠s = 80°
