Which of the following diagrams shows perpendicular lines?
Remember that a perpendicular line is a line that forms a right angle of 90 degrees with another line.
In answer B, we can identify a right angle, therefore in diagram B there is a perpendicular line.
What do the four figures below have in common?
The small square symbol at an intersection point indicates a right angle of exactly 90 degrees. This is the universal symbol that tells you two lines are perpendicular!
Absolutely! Lines can intersect at any angle from 0° to 180°. Only when they meet at exactly 90 degrees are they considered perpendicular.
Look for these visual clues:
Yes! Perpendicular lines must intersect (cross each other) to form the 90° angle. If they don't touch, we can't determine if they're perpendicular.
Without the right angle marker, you cannot assume the lines are perpendicular. The lines might intersect at any angle - always look for the square symbol or 90° marking!
