Thank you.

Answer 2

Your answer is (B) 3, 4, 5.

Explanation:

Hypotenuse (H) = 5 (The longest side of the right angle triangle is the hypotenuse of the triangle)

Perpendicular (P) = 4

Base (B) = 3

According to Pythagorus theorem,

B² + P² = H²

3² + 4² = 5²

9 + 16 = 25

25 = 25

∴ LHS = RHS

∴ Hence proved.
