CPM Homework Help : INT2 Problem 5-24

On graph paper, plot $ΔABC$ if $A(−1,−1)$ , $B(3,−1)$ , and $C(−1,−2)$ .

Enlarge (dilate) $ΔABC$ from the origin using a scale factor of $3$ . Name the image $ΔA'B'C'$ . List the coordinates of the vertices of $ΔA'B'C'$ .
Rotate $ΔA'B'C'$ $90^{\circ}$ clockwise $(\circlearrowright)$ about the origin to create $ΔA''B''C''$ . List the coordinates of the vertices of $ΔA''B''C''$ .
If $ΔABC$ is translated so that the image of point $A$ is located at $(5,3)$ , where would the image of point $B$ lie?

Use the eTool below to enlarge, rotate and translate triangle $ABC$ .
