Yes. This is a neat trick too! Just draw the shape of a five pointed star. Place one coin at each of the 5 points and 5 at each intersection in the inner pentagon. There are 4 coins in each line. I hope you can see the illustration below. The dashes were the only way to maintain the spacing of the 'coins'.

draw 9 lines and join them
Impossible. If there MUST be 5 straight lines, then there can only be 2 trees in each line. This gives 5 straight lines with 2 trees each (or 2 straight lines with 5 trees each) ** ** ** ** **
it is really easy
Two straight lines that are equidistance from each other.
it depends on how you place it, they can be. all a line segment is is a straight line, if you have two you can have parallel or crossing lines.

Yes - arrange them in the shape of a 5-pointed star. One coin goes at each point of the star, and one coin goes at the intersection of each line - making 10 coins in all. There are four coins in each line.

Perpendicular lines.
intersecting lines...

Parallel lines are 2 long straight lines that don't touch each other
Yes. You can draw infinitely many straight lines from each point.
Perpendicular Lines are two straight lines that intersect to form a 90 degrees or an right angle.Regards,
They are straight lines that intersect each other at 90 degrees
