Two shapes are congruent if they have the same size and shape. In other words, they are exact copies of each other that can be superimposed on each other without any gaps or overlaps.
The term "congruent" is commonly used in mathematics to describe objects or figures that have exactly the same shape and size. In other words, if two objects are congruent, it means that they are identical in all respects, including their angles and side lengths. This concept is often used when studying geometry, as congruent shapes can be used to create geometric proofs and solve various mathematical problems.
