Question

In the parallelogram PQRS, if angle P=70°, then the measure of angle S is

Answer 1

In parallelogram pqrs

Angle p and angle s are co-int angles.

We know the sum of co-int angles is 180

So,p+s=180

70+s=180

S=180-70

S=110

Answer 2

Given - Measure of Angle P

Find - Measure of Angle S

Solution - The measure of angle S is 110°. Assuming the angles have been named sequentially. Thus, angle P and angle S will be neighbouring angles.

As per the known fact about parallelogram, the sum of neighbouring angles is 180°. So, finding the angle S now.

Angle P + Angle S = 180°

70° + Angle S = 180°

Performing subtraction -

Angle S = 180° - 70°

Angle S = 110°

Thus, the measure of angle S is 110°.
