## 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.
