A pencil box and a book are rectangular prisms. The cross-section of a cuboid and a rectangular prism is the same. A cuboid is also called a rectangular prism. Mostly, the concept of congruent figures proves its utility when multiple items of the same specifications are to be developed at a mass level. A rectangular prism is a three-dimensional solid shape with six faces that including rectangular bases. Such practical examples tell us that congruence helps attain a level of mastery and prepares us for jobs where we apply it to meet certain objectives. The idea of congruence may further amaze you when you come across things of daily utility based on it. I suggested some congruent games to help you with applying this concept. Examples of three-dimensional geometric shapes are cubes, cuboid rectangles. Just like we read about the equality of numbers in elementary arithmetic class, we come across congruence while comparing two figures in a geometry session. Examples of two-dimensional geometric shapes include triangles, squares, rectangles, pentagons, hexagons, and octagons. This concept is useful in fields of:īesides practical utility, the congruence builds up the base for the learners and enables them to form a smoother understanding of the concepts of areas and volumes. The same intelligence helps understand the concept of congruent figures.Īlso, the figures may be in different planes still, they will be congruent when the sides, areas covered and the volume occupied are the same. Two real-life examples for congruent shapes are: 1) Two mobile phones of the same model of the same brand, 2) Two NCERT mathematics textbooks of class VII. When you find two buildings, things, or products completely identical to each other, it is because of the spatial intelligence developed. This is because congruent shapes are of equal sizes. No, when we decompose a figure, we can’t get a shape that is congruent to the original shape. Some examples of decomposing shapes in real-life are: Cutting a pizza into slices. Learning about congruence in figures is necessary to build our understanding of structures. Decomposition in Math is evident in day-to-day life. When you place them one above the other, the congruent figures overlap point-to-point. In simple words, two figures are objects that are carbon-copy of each other are said to be congruent. Moving forth, you delve deeper and find a bit more interesting topics like congruence. It is when you come across terms like symmetry, parallel and intersecting lines, etc. In this case, two triangles are congruent if two sides and one included angle in a given triangle are equal to the corresponding two sides and one included angle in another triangle. For example: Real life examples are, cigarettes in a packet are congruent to one another. Side Angle Side Side Angle Side (SAS) is a rule used to prove whether a given set of triangles are congruent. Once you are through with elementary geometry and learn about measurements, you are all set to understand the relationships between two figures. Which is an example of congruence in real life When two objects or shapes are said to congruent then all corresponding angles and sides also congruent.
