Two angle are said to be Supplementary Angles When the sum of the measures of their angles is equal to 180°. Below Figure represent Supplementary Angles. In the Above Figure, ∠ ABC = 130° and ∠ PQR = 50° Now, add both the angles and we get; ∠ ABC + ∠ PQR = 130° + 50° = 180° Since sum of measure of both the angles is equal to 180° Therefore, ∠ ABC and ∠ PQR are Supplementary Angles.
