Learn about supplementary angles -- what they are and how to identify them.
- What are supplementary angles?
- How can you find supplementary angles?
- How do you find the measures of angles x and y if the measure of angle x is three-fifths the measure of angle y and if x and y are supplementary angles?
- What is the clearing fraction approach?
- How do you solve 3/5 y + y = 180?
- How do you solve 3y + 5y = 900?
This lesson uses a geometric angle situation to set up and solve an algebraic equation to find the measures of the two angles. This is a good beginner problem if you are just learning to relate algebra equations to geometric situations.
