 Hello and welcome to the session. Let us understand the following question today. Sides of a triangle are given below. Determine if it is a right triangle. In case of a right triangle, write the length of its hypotenuse. Now before writing the solution, let us understand the Pythagoras theorem. In a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides. For example, this triangle ABC, let triangle ABC is right angled at B. Then according to Pythagoras theorem, C square is equal to AB square plus BC square. And this is our key idea to the question. Now let us write the solution. Given to us is sides 7 cm, 24 cm and 25 cm. Now let A is equal to 7 cm, B is equal to 24 cm and C is equal to 25 cm. Here we can see the largest side is C, which is equal to 25 cm. So we have A square plus B square is equal to C square. That is 7 square plus 24 square is equal to 25 square. That is 49 plus 576 is equal to 625. And we have 625 is equal to 625. Hence Pythagoras theorem is satisfied. The triangle with the given sides is a right triangle. Therefore the required answer is yes with the length of hypotenuse is equal to 25 cm. I hope you understood the question. Bye and have a nice day.
