Question

Which transformation or combination of transformations can be used to show that quadrilateral JKLM with vertices J(8, 4), K(4, 10), L(12, 12), and M(14, 10) is congruent to quadrilateral WXYZ with vertices W(8, -4), X(4, -10), Y(12, -12), and Z(14, -10)? A. a reflection B. a rotation C. a reflection followed by a dilation D. a stretch followed by a reflection E. a rotation followed by a dilation

Answer 1

Answer: a reflection

Explanation:

Answer 2

The correct answer is:

A. a reflection

Explanation:

Each point (x, y) in the pre-image is mapped to a corresponding point (x, -y) in the image. Since only the value of the y-coordinate changes, this is a reflection through the x-axis.
