Question

Which of the following pairs of angles are complementary?

Answer 1

iii one is complementary angle because it makes 90 degree angle

Answer 2

The third pair of angles are complementary (option iii).

Given,

The three diagrams.

To find,

The pair of complementary angles.

Solution,

The pair of complementary angles will be the third one (80° and 10°).

We can easily solve this problem by following the given steps.

We know that the complementary angles are the angles whose sum is 90° and supplementary angles are the angles whose sum is 180°.

Now, for the first one, the sum of two angles is (110+30)° which is 140°.

For the second one, the sum of two angels is (90+90)° which is 180°.

For the third one, the sum of two angles is (80+10)° is 90°.

Hence, the pair of complementary angles is the third one (80° and 10°).
