Complementary and supplementary angles are fundamental concepts in geometry that help us understand the relationship between angles. When exploring these angles, it is important to know how they complement each other or add up to a straight angle. Let’s delve deeper into these concepts through a worksheet that will test your knowledge and understanding of complementary and supplementary angles.
1. Define complementary angles and provide an example.
Complementary angles are two angles that add up to 90 degrees. For example, if one angle measures 30 degrees, the complementary angle would measure 60 degrees.
2. Define supplementary angles and provide an example.
Supplementary angles are two angles that add up to 180 degrees. For instance, if one angle measures 100 degrees, the supplementary angle would measure 80 degrees.
3. Find the complementary angle for an angle measuring 45 degrees.
The complementary angle for an angle measuring 45 degrees would be 45 degrees as well, as they add up to 90 degrees.
4. If two angles are complementary and one angle measures 30 degrees, what is the measure of the other angle?
If one angle measures 30 degrees, the other complementary angle would measure 60 degrees to add up to 90 degrees.
5. Determine if the following pairs of angles are complementary, supplementary, or neither: 50 degrees and 40 degrees.
The pair of angles measuring 50 degrees and 40 degrees are complementary angles as they add up to 90 degrees.
By completing this worksheet, you will enhance your understanding of complementary and supplementary angles, and how they relate to each other in geometry. Practice solving different angle problems to solidify your knowledge and skills in this area.
