Is there a picture?

jim_thompson5910 · Answer

Or does it say which two sides are equal?

anonymous · Answer

Theres no picture, it just says Isosceles Triangle, Perimeter

jim_thompson5910 · Answer

If AC is the third (unequal) side, then you have 20-8 = 12 units left which divides in half to get 12/2 = 6

So BC is 6 units

This is if BC is one of the equal sides

anonymous · Answer

So it is 6?

jim_thompson5910 · Answer

But...

If AC = BC, then BC = 8

So you can see why I'm asking for a pic or more info on this problem

So if they want this problem to be a bit more challenging, then perhaps they meant AC and BC to be different.
