Check understanding
- Translate a triangle 3 units right and 2 units down on a coordinate grid and state the new coordinates
- Reflect a shape in the x-axis and list the coordinates of the reflected vertices
- Explain how translation changes coordinates (add/subtract) while reflection changes the sign of one coordinate
“If your child draws a triangle at coordinates (1, 2), (3, 2), and (2, 4) on a grid, can they then reflect it across the x-axis and tell you the new coordinates of each corner?”
