Question

Which of the following measurements of side lengths can be used to construct a triangle?

• A. 2 m, 16 m, 6 m
• B. 4 m, 4 m, 13 m
• C. 3 m, 9 m, 2 m
• D. 12m, 13 m, 5 m

Answer 1

The correct option is D

12m, 13 m, 5 m

To construct a triangle, sum of length of two sides should be greater than third side.
So, in option D, the sum of two sides is greater than third side.
Thus, 12 m + 13m > 5 m.
