Math Problem Statement

Graph the line segments and their images after specific transformations. Tasks include rotating line segments by 90° or 180° around a given point, reflecting across y = x, and combining transformations such as rotations and translations.

Solution

Thanks for sharing the file! Let’s analyze the tasks given in this geometry exercise.


Key Exercises:

  1. Exercise 5: Rotate the line segment A(3,2)A(-3, 2) and B(1,2)B(-1, 2) 90° about P(2,0)P(-2, 0).

    • Steps:
      1. Translate P(2,0)P(-2, 0) to the origin by subtracting its coordinates from AA and BB.
      2. Perform a 90° counterclockwise rotation around the origin using the rule:
        (x,y)(y,x)(x, y) \to (-y, x).
      3. Translate back by adding P(2,0)P(-2, 0)'s coordinates to the result.
  2. Exercise 6: Rotate Q(1,1)Q(1, 1) and R(1,2)R(1, -2) 180° about P(1,2)P(1, 2).

    • Steps:
      1. Translate P(1,2)P(1, 2) to the origin.
      2. Apply a 180° rotation using the rule:
        (x,y)(x,y)(x, y) \to (-x, -y).
      3. Translate back.
  3. Exercise 7: A combination of transformations is applied to the line segment XYXY with endpoints X(3,1)X(-3, 1) and Y(4,5)Y(4, -5):

    • Rotation (180° counterclockwise about origin).
    • Translation (x, y) → (x − 1, y + 1).
      Apply these transformations sequentially.
  4. Exercise 8: A composition of:

    • Reflection over the line y=xy = x: Swap the coordinates:
      (x,y)(y,x)(x, y) \to (y, x).
    • Rotation (180° clockwise about origin).
