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 |
