2. Geometry Vocabulary Trivia Game

3. Rules Choose a topic and monetary amount of your choice. The higher the amount, the more challenging the question! The first group to answer the question correctly earns the amount. Be careful, you only have one guess per question! Look for daily doubles, where you have the opportunity to earn double the original amount of the question !
