  1. Vocabulary/Transformations Quiz review

  2. #1 Having the same size and shape congruent

  3. #2 • The figure formed by two rays with a common endpoint angle

  4. #3 • A point of a line that starts at one endpoint and extends forever ray

  5. #4 A perfectly flat surface that extends infinitely in all directions Plane

  6. #5 An exact location in space, it is usually represented as a dot, but it has no size Point

  7. #6 A part of a line between 2 endpoints Line segment

  8. #7 On an angle or polygon, the point where two sides intersect Vertex

  9. #8 A straight path that extends without end in opposite directions Line

  10. #9 A movement (slide) of a figure along a straight line Translation

  11. #10 • A change in the position or orientation of a figure Transformation

  12. #11 • A transformation of a figure that flips the figure across a line. Reflection

  13. #12 A plane formed by the intersection of a horizontal number line (x – axis) and a vertical line (y-axis) Coordinate Plane

  14. #13 • A transformation of a figure in which a figure is turned around a point Rotation

  15. #14 Reflect the triangle over the y-axis and give the coordinates of the reflected image. A B A: (-9, 9) B: (-3, 6) C: (-5, 1) C

  16. #14 answer • Reflection over the y-axis A B A’: (9, 9) B’: (3, 6) C’: (5, 1) C

  17. #15 Translate the triangle 4 units down. Give the co-ordinates of the image’s vertices. A B A: (-9, 9) B: (-3, 6) C: (-5, 1) C

  18. #15 - answer Translation 4 units down. A B A’: (-9, 5) B’: (-3, 2) C’: (-5, -3) C

  19. #16 • Rotate the image 90° counterclockwise around the origin. Give the co-ordinates of the image’s vertices. A B A: (-9, 9) B: (-3, 6) C: (-5, 1) C

  20. #16 - answer • 90° counterclockwise rotation A B A’: (-9, -9) B’: (-6, -3) C’: (-1, -5) C

  21. #17 • Reflect the triangle over the x-axis and give the coordinates of the reflected image. A B A: (-9, 9) B: (-3, 6) C: (-5, 1) C

  22. #17 - answer • Reflection over the x-axis. A B A’: (-9, -9) B’: (-3, -6) C’: (-5, -1) C

  23. #18 • If point A is (-19,7), give the ordered pair of A rotated 180 degrees around the origin. A’ (19, -7)

  24. #19 • A triangle has the following vertices: A(-2, 3) B(-5, -7) C(6,8). Rotate triangle ABC 90 ° counterclockwise around the origin and give the new coordinates. A’(-3,-2) B’(7,-5) C’(-8, 6)

  25. #20 • Give the ordered pair of point G(-3, -12) translated by (4,8). G’ (1, -4)

  26. #21 • Translate the figure below by (5, -6) and list the ordered pairs of the copy image. A B A: (-9, 9) B: (-3, 6) C: (-5, 1) C

  27. #21 answer • Translation of (5, -6) A B A’: (-4, 3) B’: (2, 0) C’: (0, -5) C

  28. #22 What type of transformation is shown? Translation

  29. #23 • What type of transformation is shown? Reflection

  30. #24 • What type of transformation is shown? Rotation

  31. #25 The co-ordinates of triangle ABC are: A (5, 2) B (5, 6) C (1, 2). List the new co-ordinates if the triangle is reflected over the x-axis. A’ (5, -2) B’ (5, -6) C’ (1, -2)

  32. #26 The co-ordinates of triangle ABC are: A (5, 2) B (5, 6) C (1, 2). List the new co-ordinates if the triangle is reflected over the y-axis. A’ (-5, 2) B’ (-5, 6) C’ (1, 2)

  33. #27 The co-ordinates of triangle ABC are: A (5, 2) B (5, 6) C (1, 2). List the new co-ordinates if the triangle is translated (-6, 3). A’ (-1, 5) B’ (-1, 9) C’ (-5, 5)

  34. #28 The co-ordinates of triangle ABC are: A (5, 2) B (5, 6) C (1, 2). List the new co-ordinates if the triangle is rotated 180° around the origin. A’ (-5, -2) B’ (-5, -6) C’ (-1, -2)
