Two shapes that are the same size and the same shape are congruent. Shapes A, B, E and G are congruent. They are identical in size and shape.

How do you know if shapes are congruent?

Having said that the best way to know if two figures are congruent is to compare the corresponding sides and corresponding angles. If these are equal, the figures are congruent.

What is an example of a congruent shape?

Usually, we reserve congruence for two-dimensional figures, but three-dimensional figures, like our chess pieces, can be congruent, too. Think of all the pawns on a chessboard. They are all congruent. To summarize, congruent figures are identical in size and shape; the side lengths and angles are the same.
