Determining the Range of the Length of the Third Side of a Triangle
Consider the given information about △ABC.
In △ABC, AB = 8 inches and BC = 9 inches.
What are the possible lengths for the third side of the triangle? Is there only one length that will fit to complete this triangle? Or are there multiple lengths that would work? In this module, you will learn how to determine the answer to this question and many more like it.
