The figures that have the same shape and size are called congruent figures. Congruent figures can be superimposed on each other, meaning that they match exactly when laid on top of one another.
For example, two triangles can be considered congruent if all their corresponding sides and angles are equal. This property can be used in various fields, such as geometry, architecture, and design, to ensure structural integrity and aesthetic balance. Understanding congruency is fundamental in mathematics as it helps in solving problems related to shape and size comparison.
