A translation slides a figure without turning or flipping it; a rotation turns it about a point; and a reflection flips it across a line of symmetry. Learners identify these transformations in drawings and on simple grids, recognizing that each preserves the figure’s size and shape while potentially changing its position or orientation; formal coordinate rules, angle measures, and compositions of transformations are not included.
A transformation changes where a shape is, but the shape keeps the same size and shape.
A triangle is shown on a grid. The same triangle appears again 4 squares to the right. It has not turned or flipped.
How was the triangle transformed?
Step 1: Compare the shapes.
The two triangles have the same size and shape.
Step 2: Look for a turn or flip.
The triangle points in the same direction in both places. It was not turned or flipped.
Step 3: Look at how it moved.
Every part of the triangle slid the same distance: 4 squares to the right.
Answer: The triangle was moved by a translation.
