If sum of two angles is 180°, they are supplementary.
For example
60° + 120° = 180°
Since, sum of both angles is 180°
So, they are supplementary
Are these angles supplementary?
68° + 132° = 200°
≠ 180°
Since, sum of both the angles is not 180°
So, they are not supplementary
Are these angles supplementary?
100° + 80° = 180°
Since, sum of both the angles is 180°
So, they are supplementary.
Are these angles supplementary?
135° + 45° = 180°
Since, sum of both the angles is 180°
So, they are supplementary.
Are these angles supplementary?
110° + 50° = 160°
≠ 180°
Since, sum of both the angles is not 180°
Are these angles supplementary?
105° + 65° = 170°
≠ 180°
Since, sum of both the angles is not 180°
So, they are not supplementary
Are these angles supplementary?
50° + 130° = 180°
Since, sum of both the angles is not 180°
So, they are not supplementary
Are these angles supplementary?
45° + 45° = 90°
≠ 180°
Since sum of both angle is not 180°
So, they are not supplementary
