Angle Pairs (and other groups)
- Jed Butler
Use the slider to change the angle measures. See which groups of angles add up to 90,180, or 360 degrees. Also look for angles that are congruent, or groups of angles that are congruent.
There are 2 answers for each. Find both. There are at least 2 ways to setup/calculate the value for each angle. Do both. 1) Which angles add up to 90 degree? 2) Which angles add up to 180 degrees? 3) Which angles are congruent?
