If the base is 10 and the two congruent sides were each 5. Then you would have a segment addition postulate (meaning that they are all on the same line). You would not have a triangle, you would have a line segment. Therefore, the sum of the 2 sides is greater than 10. So what is the smallest number that will satisfy this?
s+s>b
b=10
s+s>10
2s>10
s>5
