Question

Determine whether there are 4 pairs of perpendicular lines in the figure below?

AAABBBFFFDDDCCCEEE

Video Solution

Solution Steps

00:00 Are there 4 pairs of perpendicular lines in the drawing?
00:03 Perpendicular lines create a right angle at the intersection point between the lines
00:08 Let's mark and count all right angles to find the perpendicular lines
00:25 And this is the solution to the question

Step-by-Step Solution

Remember that perpendicular lines are lines that intersect at a 90-degree angle.

Let's mark the right angles in the drawing:

AAABBBFFFDDDCCCEEEWe can see that we have 4 pairs of perpendicular lines:

AE is perpendicular to AB

BF is perpendicular to AB

AE is perpendicular to EC

BF is perpendicular to FD

Answer

Yes
