Question

what single rigid transformation maps △abc → △edc? (1 point) dilation translation reflection rotation

Explanation:

A dilation changes the size of a figure. A translation moves a figure without rotating or reflecting it. A reflection flips a figure over a line. A rotation turns a figure around a point. Looking at \(\triangle ABC\) and \(\triangle EDC\), the orientation of the triangles is different and it seems to be turned around point \(C\).

Answer:

D. rotation
