Answer: Up, Down, Left, Right
Explanation:
A translation is when you move an object on a coordinate plane. You can move it up and down the y-axis, and left and right on the x-axis.
For example, imagine a triangle on a coordinate plane (it looks like a grid). You can move the triangle to the left, the right, up, down, or any combination of those movements. Therefore, the answer to the 4 blanks are Up, Down, Left, and Right.
