Oppositesides-Two sides of a quadrilateral are called its opposite sides if they do not have a common end point. In the given figure, (AD, BC) and (DC, AB) are two pairs of opposite sides of quadrilateral ABCD.
Complementaryangles-If the sum of two angles is 90 degrees, then they are said to be complementary angles, and they form a right angle together.
Supplementaryangles-If the sum of two angles is 180 degrees then they are said to be supplementary angles, which form a linear angle together.
