4.) TRI V has coordinates T (-2, -3), R (0, 0), and I (1, 4). After a glide reflection that includes a reflection about an axis, point T’ is at (2, -1). Based on this information, describe the glide reflection using arrow notation, then identify the coordinates of R’ and I’. 5.) You are currently at a library in New York City. To reach Central Park, you travel 8 blocks west and 15 blocks north. From Central Park, you head to a nearby school by heading 5 blocks east and 4 blocks south. How many blocks away, and in what direction(s), is this school from the library you started at? 6.) ZYXWVUTSRQ is a regular decagon with center A. a.) How many congruent triangles has the decagon been divided into, and how many degrees are there in each central angle? b.) If you were to rotate V counter-clockwise about A by 108 o , where would you end up? c.) What two rotations could you perform about A that would map ST onto ? QR d.) What is the smallest rotation you could perform about A that would map ZA onto ? TA 7.) STOP signs are in the shape of regular octagons, like the one shown here.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
