Connect points P and P Q and Q, R and R, what do you notice about the segments? 2-2. Copy the diagrams below on graph paper. Reflect the triangle across the x-axis. Reflect the triangle across the y-axis. Label the reflected points using prime notation, ie. A B C a. b. c. B A C

Reflect A across line l. d. Reflect D across line m While playing a game of pool, Montana Mike needed to hit the last remaining ball into pocket A, as shown in the diagram below. However, to show off, he decided to make the ball first hit one of the rails of the table. Copy the pool table and determine where Mike could bounce the ball off one rail so that it will land in pocket A. Draw the other two reflections of pocket A and the path the ball will follow to go in pocket A. Aim shot at reflection of A

7 2-16. Examine the triangles below. a. Are these triangles congruent? Explain how you know. b. Luis wanted to write a statement to convey that these two triangles are congruent. He started with ΔCAB, but then got stuck because he did not know the symbol for congruence. Now that you know the symbol for congruence, complete Luis s statement for him Consider square MNPQ with diagonals intersecting at R, as shown below. a. How many triangles are there in this diagram?

9 2-21.A team is working together to try to prove SAS. Given the triangles shown below, they want to prove that ΔABC ΔDEF. Congruent means that two triangles have the same size and shape, so we have to be able to move ΔABC right on top of ΔDEF using transformations, since they preserve lengths and angles, to prove they are congruent. a. Describe the transformations used to move ΔABC right on top of ΔDEF. b. Copy ΔABC and ΔDEF on your paper and draw the transformations you used to move ΔABC right on top of ΔDEF In problem 2-21 you proved SAS by finding a sequence of transformations that would move one triangle onto another.
