Two sides of an isosceles triangle have lengths of 3 and 6. what is the length of the third side?
a.) 5
b.) 6
c.) 9
d.) 3

an isosceles triangle has always two twin sides, so if one side is 3 and another is 6, there's another twin that's either 3 or 6.

now, let's take a peek at a caveat, if the twin angle missing is say 3, then the triangle has sides 3, 3 and 6, but but but, if the two slanted sides are 3 each, and the base or bottom is 6, the only way the bottom can be 6 is if the other sides lie flat on top of it, in which case we no longer have a triangle, since it'll be just 3 pancaked flat-lines, so it can't be 3, it must be 6.
