If sum of two angles is 180°, they are supplementary.

 

For example

12.jpg

 

60° + 120° = 180°

Since, sum of both angles is 180°

So, they are supplementary

 

Are these angles supplementary?

Supplementary Angles - Part 2

68° + 132° = 200°

  ≠ 180°

 

Since, sum of both the angles is not 180°

So, they are not supplementary

 

Are these angles supplementary?

Supplementary Angles - Part 3

 

100° + 80° = 180°

 

Since, sum of both the angles is 180°

So, they are supplementary.

 

Are these angles supplementary?

Supplementary Angles - Part 4

  135° + 45° = 180°

 

Since, sum of both the angles is 180°

So, they are supplementary.

 

Are these angles supplementary?

Supplementary Angles - Part 5

110° + 50° = 160°

  ≠ 180°

 

Since, sum of both the angles is not 180°

 

Are these angles supplementary?

Supplementary Angles - Part 6

105° + 65° = 170°

  ≠ 180°

 

Since, sum of both the angles is not 180°

So, they are not supplementary

 

Are these angles supplementary?

Supplementary Angles - Part 7

50° + 130° = 180°

 

Since, sum of both the angles is not 180°

So, they are not supplementary

 

Are these angles supplementary?

Supplementary Angles - Part 8

45° + 45° = 90°

≠ 180°

 

Since sum of both angle is not 180°

So, they are not supplementary
