Which figure shows perpendicular lines?
Perpendicular lines are lines that form a right angle between them.
In the drawings A+C+D, you can see that the angles formed are not right angles.
It is possible to point out a right angle in drawing B.
What do the four figures below have in common?
Look for the square corner symbol (small square) at the intersection point, or check if the lines form a perfect L-shape. The angle should look exactly like the corner of a book or paper.
All perpendicular lines intersect, but not all intersecting lines are perpendicular! Intersecting just means they cross each other. Perpendicular means they cross at exactly 90 degrees.
Yes! Perpendicular lines don't have to be horizontal and vertical. They just need to meet at a right angle. Think of an X rotated 45° - still perpendicular!
In option B, you can see one line is perfectly vertical and the other is perfectly horizontal. When vertical and horizontal lines meet, they always form 90° angles.
Sometimes drawings aren't perfect, but look for the closest to 90° angle. In math problems, there's usually a clear difference between right angles and other angles like 45° or 60°.
