Congruent shapes are figures with the same size and shape… So just looking at the order in which they're written B, vertex B corresponds, in this triangle, BCD, corresponds to vertex B in BCA, so this is the B vertex in BCA, which corresponds to the E vertex in ECD. All of the other measurements of the circles will be identical. An example of congruence. Examples of similar or congruent geometry shapes: Congruent shapes have the same size angles, side lengths, area, and perimeter. They cannot be dilated (enlarged or shrunk) and be congruent. Rectangles are very handy to have around. Usually, we reserve congruence for two-dimensional figures, but three-dimensional figures, like our chess pieces, can be congruent, too. The shapes still have congruent angles, but the line segments that make up the card are now different lengths, so the two shapes are no longer congruent. Anyway it comes from Latin congruere, "to agree". Usually, we reserve congruence for two-dimensional figures, but three-dimensional figures, like our chess pieces, can be congruent, too. For example, a congruence between two triangles, ABC and DEF, means that the three sides and the three angles of both triangles are congruent. The geometric figures themselves do not matter.

Here are two congruent figures: And here are the same congruent figures with one rotated: Here the same two figures are congruent with one translated up and away from the other: And, here are the same two congruent figures with one of them reflected (flipped): To summarize, congruent figures are identical in size and shape; the side lengths and angles are the same. The corresponding sides of congruent figures have the same length. Their angles are the same, and side lengths share the same proportions. Similar, Congruent, or Neither Example: Determine if the following solid shapes are similar, congruent, or neither.
