How Do Linear Models Handle Non-Linear Relationships?Perpendicular lines are lines that intersect at a right angle (90 degrees). This means that if you draw a line perpendicular to another line, the two lines will form an "L" shape. To understand perpendicular lines, it's essential to grasp the concept of angles and how they relate to each other. Imagine a line segment, AB. If you draw a line from point B that forms a right angle with AB, you have created a perpendicular line.
Reality: Perpendicular lines can be found in various shapes, including triangles, circles, and polygons.
While perpendicular lines intersect at a right angle, parallel lines never intersect, no matter how far they are extended. In other words, if two lines are parallel, they will never touch or cross each other.
Common questions
Reality: While perpendicular lines typically intersect at a right angle, there are cases where the intersection angle may be different.

Myth: Perpendicular lines are always at a 90-degree angle
To determine if two lines are perpendicular, you can use the following method: If the slopes of the two lines are negative reciprocals of each other, then the lines are perpendicular. For example, if the slope of one line is 2, the slope of its perpendicular line would be -1/2.
