Question

1. which sequence of transformations results in a figure congruent to the original?

a. reflection and dilation
b. reflection and rotation
c. translation and dilation
d. dilation and rotation

Explanation:

Congruent figures have identical size and shape. Transformations that preserve size and shape are rigid transformations: reflection, rotation, translation. Dilation changes the size of a figure, so any sequence with dilation cannot result in a congruent figure. Only option b uses two rigid transformations (reflection and rotation) that preserve size and shape.

Answer:

b. Reflection and Rotation
