Corresponding Parts of Congruent Figures

​

Learning Targets

I can identify corresponding parts from a congruence statement.

I can write a congruence statement.

Corresponding Sides and Angles (parts)

Corresponding parts are in the same or 'matching' positions in similar and congruent figures.

Similar Figures

Figures that are the same shape, but different sizes. All of the corresponding angles are congruent.

Similar figures have a scale factor. In the image Triangle DEF is 2 times triangle ABC.

The symbol for Similar is ~
