Points Quizzes & Trivia

This quiz contains a list of 49 definitions. You need to name the geometric vocabulary term for each definition. Many questions ask you to distinguish between a specifically correct term and others that are close but not exactly right, so be careful. Warning: Don't be too concerned about the computerized grade. For example, misspellings can be costly even if you have the right answer. If you press the back button, the computer will mark ALL your previous choices wrong!. Also, there are a few questions that can lead to answers that are not wrong but are not what the test is looking for. Print out your answers, and I'll correct your grade as needed. Good luck !
