Adding and Subtracting Angles

The video tutorial covers strategies for adding and subtracting angles. It explains how to decompose angles into smaller parts and compose them to form larger angles. The tutorial provides examples of finding unknown angle measures by adding and subtracting known angles. It includes practical problems, such as calculating the total measure of combined angles and determining unknown angles in straight angles.
