Question 38655
Using side lengths 2,3,5,7 & 11, we need to find out how many isosceles (with exactly 2 sides equal) triangles can be formed...well, start listing them...
2,2,3
3,3,2
3,3,5
5,5,2
5,5,3
5,5,7
7,7,2
7,7,3
7,7,5
7,7,11
11,11,2
11,11,3
11,11,5
11,11,7
Looks like that's it...how many? 14?
