Draw

Translate the shape so that $$A$$ goes to $$A’$$ . Use the image to draw the translated shape.

Draw

Rotate the shape $$180^\circ$$ counterclockwise around $$B$$ . Use the image to draw the rotated shape.

Draw

Reflect the shape over the line shown. Use the image to draw the reflected shape.

Open Ended

Lin says that she can map Polygon A to Polygon B using _only_ reflections. Do you agree with Lin? Explain your reasoning.
