What is an example of congruence?
If two figures can be placed precisely over each other, they are said to be ‘congruent’ figures. If you place one slice of bread over the other, you will find that both the slices are of equal shape and size. The term “congruent” means exactly equal shape and size. : the quality or state of agreeing, coinciding, or being congruent. … the happy congruence of nature and reason … Gertrude Himmelfarb. : a statement that two numbers or geometric figures are congruent. Congruence is an important mathematical idea for humans to understand the structure of their environment. Congruence is embedded in young children’s everyday experiences that allow them to develop intuitive senses of this geometric relationship. For a set of triangles to be congruent, their respective sides and angles should be equal. In case of a triangle with all respective angles equal i.e. AAA condition, the sides of the triangles may or may not be equal. Congruent angles have the same angle measure. For example, a regular pentagon has five sides and five angles, and each angle is 108 degrees. Regardless of the size or scale of a regular polygon, the angles will always be congruent.
What is a real-life example of congruence?
Pages of the same book are the real-life example of congruent shapes. All the pages of the same book are of the same shape and size. 2. Mobile phones of the same brand and same model are congruent to each other. Two figures are congruent if they have the same shape and size. Two real-life examples of congruent shapes are: 1) Two mobile phones of the same model of the same brand. 2) Two NCERT mathematics textbooks of class VII. In geometry, two figures or objects are congruent if they have the same shape and size, or if one has the same shape and size as the mirror image of the other. So, two figures are equal if they have the same points. In other words, two equal figures are exactly equal: the same figure. Congruent figures have the same shape and size (informally) but possibly different points. It states that that two triangles are said to be congruent if they are copies of each other and when superposed, they cover each other exactly. In other words, two triangles are congruent if the sides and angles of one triangle are equal to the corresponding sides and angles of the other triangle. When we look in the mirror, we see ourselves, or rather an image of ourselves that looks exactly the same as we do. We’re reflecting ourselves over the mirror so that we’re staring back at ourselves. In mathematics, this is called a reflection, and it’s an example of a congruence transformation.

In geometry, two figures or objects are congruent if they have the same shape and size, or if one has the same shape and size as the mirror image of the other. In love, congruence is when someone’s actions mirror their words. (Remember, two geometric figures are called congruent if there is an isometry taking one to the other.) Theorem (RCT: Ray Congruence Theorem). Any two rays are congruent. All congruent figures are similar, but not all similar figures are congruent. Congruence means two objects (whether two dimensional or three dimensional) are identical in size and shape. Everything about them — their angles, lengths of sides, overall dimensions — are identical.
