Which measurement is required to make a triangle along with sides 4 cm and 6 cm ? A) 1 cm B) 2 cm C) 3 cm D) 1.5 cm

Answer»

Correct option is (C) 3 cm

(A) \(\because\) 4+1 = 5 < 6

\(\therefore\) 4 cm, 1 cm and 6 cm do not form any triangle.

(B) \(\because\) 4+2 = 6 (not strictly greater than 6)

\(\therefore\) 4 cm, 2 cm and 6 cm do not form any triangle.

(C) \(\because\) 4+3 = 7 > 6, 4+6 = 10 > 3 and 3+6 = 9 > 4

\(\therefore\) 3 cm, 4 cm and 6 cm do not form any triangle.

(D) \(\because\) 4+1.5 = 5.5 < 6

\(\therefore\) 4 cm, 1.5 cm and 6 cm do not form any triangle.

Correct option is  C) 3 cm
