Video Solution

Solution Steps

00:00 Which of these lines are perpendicular to each other?
00:02 Perpendicular lines create a right angle at their intersection point
00:05 In this example, the lines form a right angle, therefore they are perpendicular
00:08 In this example, the angle is not right, therefore they are not perpendicular
00:11 In this one too
00:15 In this example, the lines form a right angle, therefore they are perpendicular
00:19 And this is the solution to the question

Step-by-Step Solution

Perpendicular lines are lines that form a right angle of 90 degrees between them.

It can be observed that in figures 1 and 3, the angles formed by the lines between them are right angles of 90 degrees.
