Geometry and discrete math...if and then statments..?

Ok, I'm having a little trouble rewriting the following into if-then statments:

a) Two distinct lines hvae at most one point in common.
f) Any point on the bisector of an angle is equidistant from the sides of the angle.

If you don't know what I mean...here's an example..

The angles at the base of an isosceles triangle are equal.

If the angles in a triangle at the base are equal then the triangle is an isosceles.

Anyway's, please help me understand the other two a, and f

Excel formula question?

cell a1=$20000 = original cost
cell a2=$2500 = working capital
cell a3=a2/(a1-a2) or $2500/(20000-2500) or 14.29% working capital
I want to put a formula into excel to figure out the working capital $ ($2500 in this example) when all I know is the % I want and the original cost. So basically working the ? backwards. I cannot figure out the formula in excel. I know how to figure out the % but I can't work it the other way to figure out the working capital $ amount when I know a %. Can anyone help?
