Can you construct a triangle of side lengths of 7 inches, 8 inches, and 15 inches?

nope, not possible
In any triangle, the sum of any of the two sides must be greater than the third side
7+8 is not greater than 15, it is equal to 15
Try by making 15 the base, and then drawing the 7 and 8 inch sides above it.
They will lie flat on the base line, thus no triangle. 
The lengths of the two sides of a triangle are given. Descride the lengths possible for the third side. 8ft, 12ft.What is the answer.
