Problems on complementary and supplementary angles are most easy to solve if you just remember the numbers 90 and 180. With the definitions given below, you will know how these numbers have been used in angles. You have ample problems to identify and calculate the missing measure of angles.
Utilize our printable complementary and supplementary angles worksheets to help build your child's skill at identifying complementary and supplementary angles, finding the unknown angles, using algebraic expressions to find angular measures, and more.
Complementary angles are two angles whose measures add up to 90 degrees, while supplementary angles are two angles whose measures add up to 180 degrees. These worksheets typically contain a variety of exercises that require students to identify, calculate, and compare these types of angles.
Two angles are complementary angles if they add up to _____ degrees. They do not have to be next to each other. When two lines intersect, four angles are created to having a point of intersection at the _____. The angles that are _____ from each other are considered to be vertical angles. They are also _____.
This page has information about complementary, supplementary, and vertical angles, with examples. At the bottom, students identify the angle type and calculate the unknown measurements.
In geometry, complementary angles are defined as two angles whose sum is 90 degrees. In other words, two angles that add up to 90 degrees are known as complementary angles. For example, if angle A is 20 degrees, then its complement angle B would be 70 degrees because 20 degrees + 70 degrees = 90 degrees.
In a right angled triangle, the two non-right angles are complementary, because in a triangle the three angles add to 180°, and 90° has already been taken by the right angle. When two angles add to 90°, we say they "Complement" each other.
