The collaborative activity Connect the shape cards with the word cards. Initial assessment task 1. Draw the shaded triangle after: a) it has been translated -7 units horizontally and +1 units vertically. Label your answer A . b) it has been reflected in the x axis. Label your answer B . c) it has been rotated 90° clockwise about (0,0). Label your answer C . d) it has been reflected in the line y = x . Label your answer D . 2. Describe fully the single transformation that: a) takes the shaded triangle onto the triangle labeled E . b) takes the shaded triangle onto the triangle labeled F . 3. Describe a single transformation that has the same effect as rotating a shape 90°clockwise, then reflecting the result in the axis. Transformations Shape F Shape G Shape D Shape E Shape C Shape B Shape A rotate 90° clockwise about (0,0) reflect in the line y = x reflect in the y axis translate +2 units horizontally -2 units vertically reflect in the line y = - rotate 90° counterclockwise about (2,0)

    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.
