two ... lines s and t and [points A and Q]
I'm thinking that this depends upon where the lines and points are located, all in relation to one another.
Sorry. We have already done it at class.
If we have two points \(\displaystyle A,B\) and a line (both points are in the same side of the line),
how could I find the point \(\displaystyle Q\) on the line which minimizes the sum: .\(\displaystyle \overline{AQ} + \overline{QB}\,?\)
