What can be said about the lines shown below?
Let's remember the different properties of lines.
The lines are not parallel since they intersect.
The lines are not perpendicular since they do not form a right angle of 90 degrees between them.
Therefore, no answer is correct.
None of the above.
The lines below are not the same size, but are they parallel?
Parallel lines never meet - they stay the same distance apart forever. If you can see the lines crossing or touching anywhere, they're definitely not parallel!
Perpendicular lines form right angles (90°) where they meet. Regular intersecting lines can meet at any angle - only when it's exactly 90° are they perpendicular.
Look for visual clues like square corner symbols (⊥) or equal spacing. But remember - unless marked, you can't assume the angle is exactly 90° just from appearance!
Sometimes lines might intersect outside the visible area of the diagram. If they're not parallel, they will eventually meet somewhere when extended far enough.
When lines are simply intersecting (but not perpendicular) or skew in 3D space, none of the standard categories apply. Always consider this option carefully!
