# Figure Game

Play the following game with a partner:

- Draw a figure on a sheet of paper, but do not show the figure to your partner. (Draw a figure such as a rhombus, an isosceles right triangle, a regular polygon, and so on.)
- Your partner needs to determine what shape you drew by asking yes-or-no questions. Your partner should not try to guess the shape until sure that only the one shape is possible.
- Once your partner guesses the figure, switch roles.

After you play the game several times, consider these questions:

- What strategies did you use?
- What types of questions were particularly helpful?

## Hint:

- What do you know about the sum of the angle measures in different figures and how the angles in different figures are related?
- What characteristics define different figures?
