Question

accelerated mathematics gr 8 | lesson: identifying and interpreting congruenc... which of the following is a correct sequence of transformations to test congruence between two shapes? a. translate, then change the size, then compare sides b. reflect, then translate, then compare corresponding parts c. dilate, then reflect, then compare angles d. rotate, then dilate, then translate

Explanation:

Congruent shapes have the same size and shape. Transformations like reflection, translation, and rotation are rigid - motions that preserve congruence. Dilating a shape changes its size and thus affects congruence. So, to test congruence, we use rigid - motions (reflection, translation) and then compare corresponding parts.

Answer:

B. Reflect, then translate, then compare corresponding parts
