Question

$\square$ PTNM is a rectangle. Write the names of the pairs of supplementary angles.

Answer 1

If the sum of the measures of two angles is 180° they are known as supplementary angles.
The measure of all the angles of a rectangle is 90°.
Hence, the pairs of supplementary angles are ∠P and ∠M, ∠T and ∠N, ∠P and ∠T, ∠M and ∠N, ∠P and ∠N, ∠M and ∠T.
