Question

From which set of dimensions could a triangle be constructed?
A.side length of 7 side length of 8 side length of 15 side
B.length of 8 side length of 5 side length of 14
C.side length of 6 side length of 3 side length of 10
D.side length of 2 side length of 6 side length of 7

Answer 1

The longest side of the triangle has to be less than the sum of the two other sides.

A ⇒ 7 + 8 = 15 
B ⇒ 8 + 5 < 14
C ⇒ 6 + 3 < 10
D ⇒ 2 + 6 > 7

The answer is D, because the longest side length (7) is shorter than the two other side lengths (2 and 6).
