hi mahathir saclolo

Welcome to the forum.

OK line one divides into two regions.

Line two crosses line one so that you've got four regions.

So the trick now is to make the third line only cut one of these regions in two.

Hint:  Put a dot where each line crosses out of the court.

I do not know if I have interpreted the problem correctly. It to me is similar to a Polya problem.

In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.
