Answer 2

Answer:

For the Proof Use Pythagoras Theorem : h² = a² + b²

(a) 8² = 4² + 3²

    64 = 16 + 9

    64 ≠ 25. So Option (a) cannot form a triangle.

(b) 9² = 8² + 6²

     81 = 64 + 36

     81 ≠ 100 . So Option (b) cannot form a triangle.

(c) 10² = 6² + 4²

    100 = 36 + 16

    100 ≠ 52. So Option (c) cannot form a triangle.
