Question

Sticks of length x units, y units, and z units form a right-angled triangle if x^2+y^2+z^2 If sticks of length a, b and c centimeters form the sides of a right-angled triangle, which of these sets of sticks will also form a right-angled triangle? (A) a/3 cm, b/3 cm, c/3 cm (B) 3a cm, 4b cm, 5c cm (C) (a + 2) cm, (b + 2) cm, (c + 2) cm (D) a^2cm, b^2cm, c^2cm

Answer 1

Answer:

A

Step-by-step explanation:

a,b,c are sides of right angled trianlge, so

a^2+b^2=c^2

dividing both sides by 9, we get

a^2/9+b^/9=c^2/9

(a/3)^2 + (b/3)^2 = (c/3)^2

this means a/3, b/3 and c/3 are sides of a right angle triangle.

in other cases the options contravenes the property of similarity of triangle.
