two angles whose sum is 90 degrees they are said to be complementary angles

two angles whose sum is 180 degrees they are said to be supplementary angles

complementary angles -

they should have a common vertex.

they should have a common arm.

the common arm should lie in between the other 2 arms.

both the angles should be acute angles.

Supplimentary angles -

they should have a common vertex.

they should have a common arm.

the common arm should lie in between the other 2 arms.

one should be acute and one should be obtuse angle or both should be right angles.

when the sum of the measures of two angles is 90 then they are called complementary angles.

when the sum of the measures of the two angles is 180 then they are called supplementary angles
