FAQs on What are Congruent Figures? Video Lecture - Class 9

1. What are congruent figures?
Ans. Congruent figures are two or more shapes that have the same size and shape. In other words, if two figures are congruent, it means that they are identical in every way and can be superimposed on each other.
2. How can we determine if two figures are congruent?
Ans. Two figures can be determined as congruent if all their corresponding sides and angles are equal. This means that if we can measure or compare the lengths of the sides and the measures of the angles in both figures, and they are all the same, then the figures are congruent.
3. Can congruent figures have different orientations?
Ans. No, congruent figures cannot have different orientations. Congruent figures must have the same size and shape, as well as the same orientation. If the orientation of the figures is different, they are not considered congruent.
4. What are some real-life examples of congruent figures?
Ans. Some real-life examples of congruent figures include two identical triangles, two identical circles, and two identical squares. These figures can be found in various objects around us, such as tiles, building blocks, and symmetrical patterns.
5. How are congruent figures useful in geometry?
Ans. Congruent figures are useful in geometry as they allow us to identify and classify shapes based on their properties. They help us understand the concept of similarity and provide a basis for proving geometric theorems. Additionally, congruent figures are used in various practical applications, such as architecture and engineering, where accurate measurements and identical shapes are crucial.
