Perpendicular lines are two lines that intersect at a 90-degree angle, forming a right angle where they meet. In geometric terms, the slopes of perpendicular lines are negative reciprocals of each other. Visually, perpendicular lines appear to be at right angles to each other, creating a distinct "L" shape where they intersect.

What does perpendicular look like?
Perpendicular is when two lines cross and form a right angle, which I hope you know what that is.
How can you tell when two lines are perpendicular?
If you measure the angle between them and it's exactly 90 degrees, then they're perpendicular. That's the definition and the requirement. Perpendicular lines form a "corner", but if you want to be technical about it, that's not a good way to tell. The angle might be only 87 degrees, or it might be 92 degrees, and when you look at it, it may look like a corner. But technically, if it's not 90 degrees then they're not perpendicular.
What does a right angle look like?
When two lines are perpendicular to each other such as L a right angle is formed which is 90 degrees.
Which shape has parallel lines but no perpendicular lines?
A rhombus has parallel lines but no perpendicular lines.
Can two lines be parellel perpendicular and intersecting at the same time?
No. If the lines are parallel they will never meet or intersect at any point. If the lines are perpendicular they do intersect, but perpendicular lines are a special case of intersecting lines. Perpendicular lines are exactly 90 degrees from each other. Intersecting lines do not haveto be perpendicular... but perpendicular lines are always intersecting.
