 Hello and welcome to the session. Let us understand the following question today. Sites of triangles are given below determine if it is a right triangle. In case of a right triangle, write the length of its hypotenuse. We have 50 cm, 80 cm and 100 cm. Now let us write the solution. Let A is equal to 50 cm, B is equal to 80 cm and C is equal to 100 cm. Here we can see the larger side is C. So according to Pythagoras theorem, A squared plus B squared should be equal to C squared. So let us see now A is 50 cm, so 50 squared plus 80 squared should be equal to 100 squared. That is 50 squared is 2500 plus 80 squared is 6400 should be equal to 10000. Now 2500 plus 6400 is equal to 8900, so it implies 8900 is not equal to 10000. Hence Pythagoras theorem is not satisfied. So the triangle with the given side is not a right angle triangle. Therefore the required answer is no. I hope you have answered the question. Bye and have a nice day.
