  1. Transformations Review M7G2: Students will demonstrate understanding of dilations, translations, rotations, and reflections of figures.

  2. Translations A translation is a transformation that SLIDES a figure.

  3. Translations Translate the points given the following rule. • Point: (-3, 11) Rule: (x + 3, y – 8) • Point: (7, -5) Rule: (x, y – 6) • (0, 3) • (7, -11) Click Here For Answer!

  4. Translations Find the rule by which each point was translated. • Point A: (2, -9) Point A’: (4, 1) • Point C: (-5, 7) Point C’: (-6, -3) • (x + 2, y + 10) • (x - 1, y - 10) Click Here For Answer!

  5. Reflections A reflection is a transformation in which a figure is FLIPPED.

  6. Reflections Reflect the points given the following rule. • Point: (-12, 21) Rule: Over the x- axis • Point: (7, -8) Rule: Over the y- axis • (-12, -21) • (-7, -8) Click Here For Answer!

  7. Rotations A rotation is a transformation that TURNS a figure about a point.

  8. Dilations A dilation is a transformation in which a figure is ENLARGED or REDUCED.

  9. Dilations Dilate the points given the following rule. • Point: (4,10) Rule: 90o Clockwise • Point: (-9, -1) Rule: 90o Counter-Clockwise • Point: (2, 5) Rule: 180o • (10, -4) • (1, -9) • (-2, -5) Click Here For Answer!

  10. Dilations Dilate the points given the following rule. • Point: (5, 15) Rule: 50% • Point: (8, -4) Rule: 125% • Point: (-12, 16) Rule: 75% • (2.5, 7.5) • (10, -5) • (-9, 12) Click Here For Answer!

  11. Dilations Find the dilation percentage for each point and its image. • Point T: (-2, -8) Point T’: (-3, -12) • Point A: (-20, 4) Point A’: (-15, 3) • 66% • 133% Click Here For Answer!
