Supplementary angles

Right Angle Acute Angle Obtuse Angle Zero Angle Straight Angle
Complementary Angles Supplementary angles Adjacent Angles Vertical / Vertical Opposite Angles Linear Pair

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.
