Congruent
Having the same size and shape
In geometry, congruent is a term used to describe two or more shapes or figures that have the same size and shape. More formally, two shapes are said to be congruent if they have exactly the same measures for all of their corresponding sides and angles. The term corresponding means that you can match each side and angle of one shape to a side and angle of the other, so that they overlap perfectly.
For example, two triangles are said to be congruent if all of their corresponding sides and angles are equal. If you superimpose one of the triangles over the other, they will perfectly overlap. This means that you could take one triangle and place it on top of the other triangle without changing its shape or size.
Congruent shapes are often used in geometry problems and proofs, because the fact that they have the same size and shape means that they have all of the same properties. For example, if two triangles are congruent, then they have the same area, perimeter, and angles. This can make it easier to solve problems involving these shapes, since you can use properties that you know from one shape to solve the other.
In summary, congruent is a term used to describe two or more shapes that have the same size and shape, with all corresponding sides and angles being equal.
