Geometry Problem: Which Lines Form Perfect Right Angles?

Question

Which lines are perpendicular to each other?

00:00 Which lines are perpendicular?

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

00:05 In this example, the angle between the lines is unknown

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

00:15 In this example, the lines never intersect and therefore are parallel

00:26 And this is the solution to the question

Let's remember that perpendicular lines are lines that form a right angle of 90 degrees between them.

The only drawing where it can be seen that the lines form a right angle of 90 degrees between them is drawing A.
