Lesson 4

Coordinate Moves

Here are some points.
$Points $A$, $B$ and $C$ on a coordinate plane, origin $O$.$

What are the coordinates of $A$, $B$, and $C$ after a translation to the right by 4 units and up 1 unit? Plot these points on the grid, and label them $A’$, $B’$ and $C’$.
Here are some points.
$Points $D$, $E$ and $F$ on a coordinate plane, origin $O$.$

What are the coordinates of $D$, $E$, and $F$ after a reflection over the $y$ axis? Plot these points on the grid, and label them $D’$, $E’$ and $F’$.
Here are some points.
$Points $G$, $H$ and $I$ on a coordinate plane, origin $O$.$

What are the coordinates of $G$, $H$, and $I$ after a rotation about $(0,0)$ by 90 degrees clockwise? Plot these points on the grid, and label them $G’$, $H’$ and $I’$.
