Draw the line of reflection. From a point on the shape, count how far it is vertically from the line of reflection. Count the same amount horizontally on the other side of the line and plot the point.

Transformations change the size or position of shapes. Scale factors can change the size of the shape. When a shape is translated, it is moved up or down and/or left or right. Every point in the shape ...

Each challenge shows a red shape and its image (outline) under a single unknown transformation (either a reflection, rotation, or translation). Drag the red shape to observe the behavior of its image.
