Identifying Perpendicular Lines: 90-Degree Angle Recognition in Geometric Figures

Question

Which figure shows perpendicular lines?

00:00 Which lines are perpendicular?

00:02 Perpendicular lines create a right angle at their intersection point

00:05 In this example, the angle is not right

00:08 In this example, the lines form a right angle, therefore they are perpendicular

00:11 In this example, the angle is not right

00:14 And in this one too

00:17 And this is the solution to the question

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.
