Question

The three sides of a triangle are given to be 12 cm, 7.5 cm and 14.5 cm. Is this triangle a right triangle? If so, which side is the hypotenuse.

Answer 1

here,
the square of the biggest side = 14.5²
= 210.25cm.sp. ......(1)
the sum of square of the remaining side= 7.5² + 12²
= 200.25. ...(2)
therefore from (1) & (2)
14.5² ≠ 7.5² + 12²
