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
