Lesson 4: Practice Problems

Problem 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 $C^{'}$ .
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 $F^{'}$ .
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 $I^{'}$ .
