Angle Relationships and Measurements

The video tutorial explains how to add and subtract angles to find total or missing angles in figures. It demonstrates calculating a missing angle when two angles sum to 120 degrees and finding the difference between angles made by kites with the ground. The tutorial uses diagrams and equations to illustrate these concepts, emphasizing subtraction to determine angle differences.

What can you use to find the total or missing angles in a figure?

• Only addition

• Only subtraction

• Addition and subtraction

• Multiplication and division
