Name: Review for Final 2021 Period: Geometry CP Note to student: This packet should be used as practice for the Geometry CP Final Exam. This should not be the only tool that you use to prepare yourself for the exam. You must go through your notes, re-do homework problems, class work problems, formative assessment problems, and questions from your tests and quizzes throughout the year thus far. Section 1 1) Classify each statement as true or false, and explain your reasoning in each false case.
a) Two planes intersect in only one point. __________________________________
b) A ray starts at one point on a line and goes on forever. ______________________
c) The intersection of 2 planes is one line __________________________________
d) Any four points are collinear. __________________________________________
2) Use the figure below for #6- 14. Note that 𝑅𝑁⃡ pierces the plane at N. It is not coplanar with V.
a) Name two segments shown in the figure. b) What is the intersection of 𝑪𝑴⃡ and 𝑹𝑵⃡? c) Name three collinear points. d) What are two other ways to name plane V? e) Are points R, N, M, and X coplanar? f) Name two rays shown in the figure. g) Name the pair of opposite rays with endpoint N. h) AN is the same as NA. True or False? i) ANX names a plane. True or False?
