Answer 1

SOLUTION

TO DETERMINE

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

EVALUATION

First we learn about vertically opposite angles.

When two lines intersect each other then four angles are created

Among the four angles , the pair of angles which lie on the opposite sides of the point of intersection are called vertically opposite angles.

Also it is to be noted that Vertically opposite angles are always equal.

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

∠r = 80°

∴ ∠s = ∠r = 80°

FINAL ANSWER

∠s = 80°
