# Make a Table of Angle Sums

On a blank sheet of paper, draw a pentagon and a hexagon using the ruler side of your protractor.

- What do you think the sum of the angles for each figure is?
- Measure each angle of the pentagon and hexagon. Find the angle sum for each figure.
- Complete the first four rows of the table based on what you know. Make a prediction for the last row. What do you notice? Do you see a pattern in the way that the angle sums increase?
