Watch the teacher solve the problem with clear explanations
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
