Question

q1 - accelerated mathematics gr 8 | lesson: creating congruent figures using sequences... target due: last friday 0% if a figure is reflected over the y - axis and then translated 4 units up, which of the following describes the combined transformation? a. reflection and translation b. rotation and dilation c. reflection and dilation d. translation and rotation how does translating a figure affect its congruence? a. it changes the shape.

Explanation:

1. For the first question, the operations described are reflection over the y - axis and translation 4 units up, so the combined transformation is reflection and translation.
2. For the second question, translation is a rigid transformation that only moves a figure without changing its shape, size or angles, so it does not affect congruence.

Answer:

1. a. Reflection and Translation
2. It does not affect congruence (not listed in the options provided, but the correct concept; if we assume the closest correct - like option was missed, and we go by the fact that translation doesn't change shape as in the options, we can say none of the above as the best response among the given ones is wrong). If we have to pick from the given options, none of them are correct as translation doesn't change the shape.
