Complementary angles are exactly two angles that add up to 90°.
Let’s get some examples and images to get some more understanding.
EXAMPLES FOR MORE UNDERSTANDING
Here are some more examples to help you understand.
25° and 65° added together will make a complementary angle because 25° + 65° = 90°
70° and 20° added together will make a complementary angle because 70° + 20° = 90°
60° and 40° will not make a complementary angle because 60° + 40° = 100°, not 90°.
