This versatile worksheet can be customized according to individual learning preferences, converted into flash cards for practical application, or employed in a distance learning scenario for a flexible, interactive math learning experience.
Student objectives
- Practice finding complementary angles by subtracting from 90°
- Practice finding supplementary angles by subtracting from 180°
- Learn the difference between complementary (add to 90°) and supplementary (add to 180°) angle pairs
Everyday practice
- Adjust a picture frame or shelf bracket to make a right angle (90°) using the two angles that meet at the corner.
- Figure out the other angle when a door is partly open and you know the angle between the door and the wall on one side of the straight line.
- Use a protractor in a craft or model project to draw an angle, then find the angle needed to complete a 90° or 180° turn.
- Check the angles in a simple roof or ramp sketch where two angles form a straight line and one angle is labeled.
