Question

A triangle has two sides that measure 4ft. and 3ft. Which could be the measure of the 3rd side?

Answer 1

In order to form a triangle, the third side must be at least greater than the difference of the other two sides
4 - 3 = 1 So the third side must be greater than 1 foot and the third side must be less than the sum of the other two sides
4 + 3 = 7 So, the third side must be less than 7

1 < third side < 7
