Intersecting mean two lines crossing perpendicular means two lines crossing, but making a 90 degree angle parallel means two lines side by side that DO NOT cross (if this answer is too late then sry )
Intersecting is where two lines cross at any angle. Perpendicular means two lines cross at exactly a 90-degree angle Parallel indicates that the two lines have the same slope and never cross.
find prime factors to get the inbetween numbers for product, and choose the one that has a difference of 20, and it should be 5 and 25, both requirements are met.
