divide the tennis court into 5 parts
each part has 3 balls
use only 3 straight lines in dividing the tennis
there are 15 balls
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.
If it ain't broke, fix it until it is.
A number by itself is useful, but it is far more useful to know how accurate or certain that number is.
