Question

2. Two adjacent angles of a parallelogram are in the
ratio 1: 1. Find the measures of all the angles.​

Answer 1

Answer:

90°,90°,90°,90°

Step-by-step explanation:

as we have given that its a parallelogram and ratio of adjacent angle is 1:1

so that 360/4= 90

Answer 2

Answer:

• Measure of all angles of parallelogram is 90°.

Step-by-step explanation:

Given :-

• Two adjacent angles of parallelogram are in ratio 1:1.

To find :-

• Measure of all angles of parallelogram.

Solution :-

Let, Angles of parallelogram be 1x or x and x.

We know,

Sum of two adjacent angles of parallelogram are supplementary or we can say 180°.

So,

⇒x + x = 180°

⇒2x = 180°

⇒x = 180°/2

⇒x = 90°

Angles :-

• x = 90°

• x = 90°

If measure of two angles of parallelogram are 90°. Then, Measure of other two angles is also 90°.

Thus,

All angles measure is 90°.
