FAQs on 06 - Pythagoras Theorem (explanation) - Class 10 - Maths Video Lecture

1. What is Pythagoras Theorem?
Ans. Pythagoras Theorem states that in a right-angled triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.
2. How is Pythagoras Theorem represented mathematically?
Ans. Pythagoras Theorem is represented mathematically as a^2 + b^2 = c^2, where 'a' and 'b' are the lengths of the two sides of the right-angled triangle, and 'c' is the length of the hypotenuse.
3. How can Pythagoras Theorem be used to find the length of a side in a right-angled triangle?
Ans. To find the length of a side in a right-angled triangle using Pythagoras Theorem, we can rearrange the formula to solve for the unknown side. For example, if we know the lengths of the other two sides, we can substitute those values into the formula and solve for the unknown side.
4. Can Pythagoras Theorem be used in any type of triangle?
Ans. No, Pythagoras Theorem can only be used in right-angled triangles. It does not apply to other types of triangles, such as equilateral or scalene triangles.
5. How is Pythagoras Theorem used in real-life applications?
Ans. Pythagoras Theorem is used in various real-life applications, such as construction, architecture, navigation, and engineering. It helps in calculating distances, determining the lengths of sides in structures, and solving problems involving right-angled triangles in practical situations.
