Question from Stephanie, a student:

I have an isosceles triangle. The two equal sides are given to me, but not the base. The equal sides are 12. I have to find the base of the triangle. Help!!


Take a pair of scissors. Each blade of the scissors is the same length, say 15 cm. So the two blades and the gap between the ends is an isosceles triangle. How wide is the gap between the ends of the pair of scissors?

You don't have enough information to answer this question.
