Question

Randy drew a triangle on a construction paper. Two sides of the triangle measured: 4 inches and 15 inches. Which could be the measure of the third side of the triangle Randy drew?

Answer 1

if 2 sides of a triangle are 4 inches and 15 inches

the 3rd side can not be greater than the sum of the other two sides: 4+15 =19

and it cannot be less than their difference: 15-4 = 11

3rd side is somewhere between 11 and 19 inches long
