Question

the transformation maps δabc to δabc. which statement is true about the transformation? it is isometric because not all side lengths and angle measures remained the same. it is isometric because all side lengths and angle measures remained the same. it is not isometric because not all side lengths and angle measures remained the same. it is not isometric because all side lengths and angle measures remained the same.

Explanation:

Step1: Recall isometric - transformation definition

An isometric transformation (rigid - motion) is a transformation that preserves side - lengths and angle - measures.

Step2: Analyze the given triangles

From the figure, we can see that the side - lengths and angle - measures of $\triangle ABC$ and $\triangle A'B'C'$ are the same. The markings on the sides and angles indicate congruence.

Answer:

It is isometric because all side lengths and angle measures remained the same.
