9-1: TEKS Practice

  • 1. Multiple Representations Which figure is the image of ΔDEF after a translation? Use arrow notation to show how each vertex of ΔDEF maps to its image after the translation.

    A graph of four triangles.

  • 2. The coordinates of ΔDEF are D(4, 3), E(7, 3), and F(6, 8). If you translate ΔDEF 4 units left and 3 units up, what are the coordinates of F′?

  • 3. 

    • a. Describe the location of the image of the figure under the given translation relative to the original figure.

      open x comma y close rightwards arrow open x plus 3 comma y plus 2 close

      A graph of a triangle with vertices (−8, 3), (−5, −1), and (−3, 4).

      • A. The image is up and to the left.

      • B. The image is up and to the right.

      • C. The image is down and to the right.

      • D. The image is down and to the left.

    • b. Choose the graph that shows the figure and the image under the given translation.

      • A. Original triangle and translation choices

      • B. Original triangle and translation choices

      • C. Original triangle and translation choices

  • 4. 

    • a. Estimation Estimate the vertices of ΔTUV.
