Complementary Angles

Last updated at April 16, 2024 by

If sum of two angles is 90°, they are complementary

For example

30° + 60° = 90°

 

Since sum of both angles is 90°

So, they are complementary   

 

Are these angles complementary?

Complementary Angles - Part 2

 

35° + 65° = 100°

 ≠ 90°

Since sum of both angles is not 90°

So, they are not complementary    

 

Are these angles complementary?

Complementary Angles - Part 3

 

45° + 45° = 90°

Since sum of both angle is 90°

So, they are complementary   

 

 

Are these angles complementary?

Complementary Angles - Part 4

70° + 20° = 90°

 

Since sum of both angle is 90°

So, they are complementary   

 

Are these angles complementary?

Complementary Angles - Part 5

75° + 25° = 100°

         ≠ 90°

 

Since sum of both angles is not 90°

So, they are not complementary   

 

Are these angles complementary?

Complementary Angles - Part 6

48° + 52° = 100°

                ≠ 90°

 

Since sum of both angles is not 90°

So, they are not complementary   

 

Are these angles complementary?

Complementary Angles - Part 7

 

35° + 55° = 90°

 

Since sum of both angles is 90°

So, they are complementary
