Vertical angles are congruent or equal. Right Angle. An angle that measures exactly 90°. Perpendicular Lines. If two intersecting lines or line segments form 90° angles around the point of intersection. Shown by ⊥ symbol. Perpendicular Lines Theorem. If two lines intersect and one of the angles is 90°, then the lines are perpendicular.

- Summary
Two lines are perpendicular when they meet at a right angle (90°). To find a perpendicular slope: In other words the negative reciprocal
When we multiply a slope m by its perpendicular slope −1m we get simply −1. So to quickly check if two lines are perpendicular: Like this:
The previous methods work nicely except for a vertical line: In this case the gradient is undefined (as we cannot divide by 0): m = yA − yBxA − xB = 4 − 12 − 2 = 30= undefined So just rely on the fact that: 1. a vertical line is parallel to another vertical line. 2. a vertical line is perpendicular to a horizontal line (and vice versa).

Parallel lines are the lines that never intersect each other. Thus, two parallel lines always maintain a constant distance between them. Perpendicular lines are the two lines that intersect each other at a right angle. We come across examples of parallel lines and perpendicular lines in daily life. Observe the white lines or stripes in a marked ...
- Parallel lines are the lines which never intersect each other even if we extend them infinitely whereas intersecting lines meet each other at a point.
- No. Intersecting lines can meet at any angle. But all perpendicular lines are intersecting lines.
- The common characteristic is that both have straight lines.
- Yes. A figure can have both Parallel and Perpendicular Lines. Some examples are: Letter H, Letter E, Square, Rectangle etc.
- A rectangle has 2 pairs of parallel lines and 4 pairs of perpendicular lines.
Parallel and perpendicular lines are an important part of geometry and they have distinct characteristics that help to identify them easily. Two lines are termed as parallel if they lie in the same plane, are the same distance apart, and never meet each other. Perpendicular lines are intersecting lines that always meet at an angle of 90°.
