FAQs on Examples: Pythagoras Theorem- 1 Video Lecture - Mathematics (Maths) Class 7

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 lengths of the other two sides. It can be written as a^2 + b^2 = c^2, where 'a' and 'b' are the lengths of the two legs of the triangle, and 'c' is the length of the hypotenuse.
2. Who discovered Pythagoras Theorem?
Ans. Pythagoras Theorem is named after the ancient Greek mathematician Pythagoras, who is credited with its discovery. However, there is evidence that this theorem was known and used by other ancient civilizations, such as the Babylonians and the Egyptians, even before Pythagoras.
3. How can Pythagoras Theorem be applied in real life?
Ans. Pythagoras Theorem has various practical applications in everyday life. Some examples include using it to calculate distances, such as finding the shortest path between two points on a map, measuring the diagonal of a rectangular object, determining the height of a tall structure, or even in construction and engineering to ensure accurate angles and measurements.
4. Can Pythagoras Theorem be used for any type of triangle?
Ans. No, Pythagoras Theorem is specifically applicable to right-angled triangles only. It does not hold true for other types of triangles, such as acute or obtuse triangles, where the angles are not 90 degrees.
5. Are there any alternative forms of Pythagoras Theorem?
Ans. Yes, there are alternative forms of Pythagoras Theorem that can be derived from the original equation. Some of the alternative forms include the Law of Cosines and the Law of Sines, which are used to solve triangles in more general cases where the angles are not necessarily 90 degrees. These alternative forms offer solutions for non-right-angled triangles.
