Question

Two sides of an isosceles triangle measures 10 and 10. What is true about the third side?

Answer 1

< 20 (got it correct on my test)

Explanation:

According to the Triangle Inequality Theorem, the third side must be smaller than the sum of 10 + 10 = 20.

Answer 2

The 3rd side is not the same length of the first 2 sides.
