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.
