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?
35° + 65° = 100°
≠ 90°
Since sum of both angles is not 90°
So, they are not complementary
Are these angles complementary?
45° + 45° = 90°
Since sum of both angle is 90°
So, they are complementary
Are these angles complementary?
70° + 20° = 90°
Since sum of both angle is 90°
So, they are complementary
Are these angles complementary?
75° + 25° = 100°
≠ 90°
Since sum of both angles is not 90°
So, they are not complementary
Are these angles complementary?
48° + 52° = 100°
≠ 90°
Since sum of both angles is not 90°
So, they are not complementary
Are these angles complementary?
35° + 55° = 90°
Since sum of both angles is 90°
So, they are complementary
