5-138.

On graph paper, draw $ΔABC$ if $A(3,2)$, $B(-1,4)$, and $C(0,-2)$.

1. Find the perimeter of $ΔABC$.

$\sqrt{20} + 5 + \sqrt{37} \approx 15.55 \text{ units}$

2. Dilate $ΔABC$ from the origin by a factor of $2$ to create $ΔA'B'C'$. What is the perimeter of $ΔA'B'C'$?

3. If $ΔABC$ is rotated $90^{\circ}$clockwise $\left(\circlearrowright\right)$ about the origin to form $ΔA''B''C''$, name the coordinates of $C''$.
