Check whether the following can be the sides of a right angled triangle AB = 25 cm, BC = 24 cm, AC = 7cm.
In a right angled ΔABC, AB = 25 cm, BC = 24 cm and AC = 7 cm.
We know that in a right angled triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.
⇒ In ΔABC, AB2 = BC2 + AC2
⇒ 252 = 242 + 72
⇒ 625 = 576 + 49
⇒ 625 = 625
∴ The given sides can be the sides of a right angled triangle.
