The sides of a `DeltaABC ` measure 7 cm, 24 cm and 25cm. What type of a triangle is ABC ?

Answer» Since no two sides are equal, ABC is a scalene triangle.
Further, `7^(2)+24^(2)=25^(2)`
Since the square of the longest side is equal to the sum of the square of the other two sides, ABC is right-angled triangle.
