Lesson 4

1. Here are some points.

   

   

   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 $C’$.

2. Here are some points.

   

   

   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 $F’$.

3. Here are some points.

   

   

   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 $I’$.

Describe a sequence of transformations that takes trapezoid A to trapezoid B.

Reflect polygon $P$ using line $\ell$.
