What's on the worksheet

  1. Find the image of each point under a dilation at the origin:
    (5, −2), k = 3(−12, 20), k = \dfrac14(−6, −10), k = 1.5(0, 7), k = \dfrac27(6, −9), k = \dfrac53
  2. Find images on a number line with center -1 and scale factor 3, and the number with a given image.
  3. Find distances from the spot when Hannah zooms a map by a factor of 4.
  4. Find the original point from its image, center and scale factor.
  5. Decide which points could be the image of P and give the scale factor.
  6. Find the center of a dilation by drawing lines through matching points of two triangles.
  7. Dilate a segment about its midpoint and find the new length.
