If an isosceles triangle has 2 side lenghts of 7 inches and 14 inches, what is the third side? Show you work.

Answer 1

having being looking at this question for a while it imposible to find the third side unless at least angle is given...typo i guess

Answer 2

The short sides cannot be 7, because then you would have a base of 14, and a height of zero. (The two 7" sides would lie down flat on the base.)

Remember that any side must be less than the sum of the other two sides.

So, the base must be 7 and the two equal sides are 14. A tall thin triangle.

So, the 3rd side is 14.
