Line Pattern Recognition: Comparing Four Geometric Configurations

Question

What do the four figures below have in common?

00:03 What do all these drawings have in common?

00:06 Perpendicular lines meet to form a right angle at their intersection.

00:11 In this example, the lines create a right angle, so they are perpendicular.

00:17 And in this one, they are also perpendicular.

00:20 These lines are perpendicular too.

00:23 Again, we see perpendicular lines here.

00:27 All lines are perpendicular to each other. That's the answer to our question!

Upon observation we can see that all the lines form a right angle of 90 degrees with each other.

Typically lines that form a right angle of 90 degrees with each other are perpendicular and vertical lines.

Therefore, the correct answer is a.

All the figures are perpendicular
