2-68.

Plot $ΔABC$ on graph paper if $A(6,3)$, $B(2,1)$, and $C(5,7)$.

1. $ΔABC$ is rotated about the origin $180º$ to become $ΔA'B'C'$. Name the coordinates of $A'$$B'$, and $C'$.

2. This time $ΔABC$ is rotated $180°$ about point $C$ to form $ΔA''B''C''$. Name the coordinates of $B''$.

3. If $ΔABC$ is rotated $90º$ clockwise ($\circlearrowright$) about the origin to form $ΔA'''B'''C'''$, what are the coordinates of point $A'''$?

Use the eTool to graph and rotate triangle $ABC$.
