Sum of the Interior Angles of a Triangle
- Ashlyn Thompson
Grab each of the points, and move them to increase or decrease their respective angles. Pay close attention to the sum of the angles.
1) What happens when the angle size increases for each of the angles? Do the other two increase, decrease or remain the same? 2) What happens to the sum of the angles? 3) Is there anyway to get the some of the interior angles to be more than 180 degrees? If so, how?
