Which figure(s) show intersecting lines?
Lines that intersect each other are lines that meet or cross each other.
The diagrams showing lines that cross each other are 1 and 3.
In diagram 2, the lines are perpendicular and vertical to each other, while in drawing 4, the lines are parallel to each other.
1 and 3
The lines below are not the same size, but are they parallel?
Intersecting lines meet or cross each other at one point, while parallel lines never meet - they stay the same distance apart forever, like railroad tracks.
Yes! Perpendicular lines are a special type of intersecting lines that meet at exactly 90° angles. But not all intersecting lines are perpendicular - they can cross at any angle.
Look for lines that cross each other or meet at a point. You'll see an X-shape, T-shape, or plus sign (+) pattern where the lines come together.
Figure 2 shows perpendicular lines that don't actually meet - they form a cross pattern but are separate. Figure 4 shows parallel lines that never cross each other.
Almost doesn't count! Lines either intersect (meet at a point) or they don't. If they're very close but don't actually touch, they're not intersecting.
