Congruence In Geometry: Definition, Properties, And Applications

Congruent

Have the same measure

Congruent refers to having the same shape, size, and measurements. It is a term used to describe geometric figures, such as triangles, squares, or circles, that are identical in their measurements and shape. Congruent figures will have the same angles, sides, and area, but may be located in different positions, or may even be oriented differently.

For example, two triangles are congruent if they have the same three sides and the same three angles. Similarly, two circles are congruent if they have the same radius. To show that two geometric figures are congruent, we typically use labels, symbols, or markings to indicate that each corresponding side, angle, or measurement is the same. The symbol ≅ is commonly used as a shorthand for congruence.

When working with congruent figures, we can often use properties that apply to one figure to solve problems involving another congruent figure. Additionally, if we can prove that two figures are congruent, we can use this information to make inferences about their properties and relationships. Congruence is an important concept in geometry and is fundamental to many applications in fields such as engineering, architecture, and design.
