What two transformations were completed to move triangle A(-5,2) B(-3,2) C(-3,5) to triangle X(0,-6) Y(0,-4) Z(-3,-4)? Include the name of the transformation and by how much. Example- it was Rotated by 180 degrees and reflected over line x=y

To determine the transformations that moved triangle A(-5,2) B(-3,2) C(-3,5) to triangle X(0,-6) Y(0,-4) Z(-3,-4), we can analyze the changes in coordinates.

  1. Translation:

    • To move triangle ABC to the left 5 units and down 8 units.
    • The transformation can be described as: \[ \text{Translation} \left( x \to x + 5, , y \to y - 8 \right) \]
    • For example:
      • A(-5, 2) translates to A' (0, -6)
      • B(-3, 2) translates to B' (2, -6)
      • C(-3, 5) translates to C' (2, -3)
  2. Reflection:

    • After this translation, we can see triangle ABC was then reflected over the line y = -4.
    • The reflection of points (for example) involved making the y-coordinates become negative.
    • The transformation can be described as: \[ \text{Reflection over } y = -4 \]

Thus, the transformations that moved triangle A(-5,2) B(-3,2) C(-3,5) to triangle X(0,-6) Y(0,-4) Z(-3,-4) are:

  1. Translated by (5, -8)
  2. Reflected over the line \( y = -4 \)
