Exploring Congruent Polygons

The video tutorial introduces congruent figures, focusing on congruent polygons. It explains that congruent polygons must have all corresponding angles and sides congruent. The tutorial provides examples to illustrate these criteria and distinguishes between congruent and similar figures. It also covers how to write congruent statements, emphasizing the importance of order. The video concludes with exercises on matching congruent shapes and writing appropriate congruent statements.

What must be true for two polygons to be congruent?

• All sides must be proportional.

• All angles must be right angles.

• All sides must be equal in length.

• All corresponding angles and sides must be congruent.

In the given example, why are the shapes with sides 6, 7, and 10 not congruent to the shapes with sides 12, 14, and 20?

• Because they are not the same shape.

• Because their corresponding sides are not congruent.

• Because their sides are not proportional.

• Because their angles do not match.
