Question

triangle $rst$ is rotated $90^{\circ}$ in a clockwise direction. what is the name of the image after the rotation?
$srt$
$rst$
$srt$
$rst$

Explanation:

When a figure is rotated, each vertex of the original figure is mapped to a corresponding image vertex, denoted by adding a prime symbol (') to the original vertex letter. The order of the vertices in the image name must match the order of the original figure's vertices. For triangle RST, its rotated image will have vertices R', S', T' in the same corresponding order.

Answer:

D. R'S'T'
