Question

A triangle has two 12‑centimeter sides. Which of the following CANNOT be the length of the third side? A. 12 cm B. 6 cm C. 24 cm D. 18 cm

Answer 1

C. 24m cannot be the length of the third side

Explanation:

the sum of the lengths of any two sides of a triangle is greater than the length of the third side.

a = 12, b = 12

c < a + b

c < 24

therefore based on the choices...

C. 24m cannot be the length of the third side.

Answer 2

C.

Explanation:

The sum of two sides have to be greater than than the third (Triangle Inequality Theorem). 24 is equal to 24, not greater.
