triangle abc is congruent to △abc by the hl theorem. what single rigid transformation maps △abc onto △abc? dilation reflection rotation translation

Answer

Brief Explanations:

A dilation changes the size, not a rigid - transformation. A translation moves the figure without flipping or rotating. A rotation turns the figure around a point. A reflection flips a figure over a line. Given the orientation of $\triangle ABC$ and $\triangle A'BC'$, a reflection over the line containing segment $BC$ will map $\triangle ABC$ onto $\triangle A'BC'$.

Answer:

B. reflection
