Intersecting lines
Intersecting lines are distinct lines in one plane that meet at exactly one point.
Continue from this idea into connected AXIO math.
What it means
Extend both straight lines in both directions. If they meet, the meeting place is their intersection point. The crossing can make any angle; it does not have to be a square corner.
Remember it
Two straight paths cross once, and the crossing point belongs to both.
Example
Draw a line through A and B. Draw another line through C and D so it crosses the first at P. The lines intersect, and P is their only shared point.
Watch for
Two short drawn segments may not touch even though the complete lines containing them would intersect when extended.
Common mix-up
Perpendicular lines are intersecting lines that meet at a right angle; other intersecting lines do not.
Exact meaning
In Euclidean geometry, two distinct coplanar lines are intersecting lines when they share exactly one point, called their point of intersection.
