Question

In parallelogram ROCK shown below, m angle ROS=65^ and m angle OCK=70^ . What is the measure of angle R ? Explain why

Answer 1

angke R is 70

Explanation:

opposite angle of a parallelogram are equal.

I.e. angle C = angle R = 70

Answer 2

70

Explanation:

In a parallelogram, (I) opposite angles are congruent.

(II) Adjacent angles are supplementary.

(III) Opposite sides are equal and parallel.

(Iv) Diagonals bisect each other

Angle R and angle C are opposite angles as they don't share any arm's(sides).

∠R = ∠C = 70
