Similar Figures

Front

What are similar figures?

Back

Similar figures are shapes that have the same shape but may differ in size. Their corresponding angles are equal, and the lengths of their corresponding sides are proportional.

If the scale factor is 2, what does this indicate about the size of the new figure compared to the original?

Back

The new figure is an enlargement of the original figure, twice its size.
