4-121.

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

1. Enlarge (dilate) $ΔABC$ from the origin so that the ratio of the side lengths is $3$. Name this new triangle $ΔA'B'C'$. List the coordinates of the vertices of $ΔA'B'C'$.

2. Rotate $ΔA'B'C'$ $90º$ clockwise $(\circlearrowright)$ about the origin to find $ΔA''B''C''$. List the coordinates of the vertices of $ΔA''B''C''$.

3. If $ΔABC$ is translated so that the image of $A$ is located at $(5,3)$, where would the image of $B$ lie?

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