Perpendicular lines
form 4 right angles
Perpendicular lines are two lines that intersect each other at a right angle, which is exactly 90 degrees. In other words, if one line is positioned vertically, the other one would be positioned horizontally.
When two lines are perpendicular, they have a special characteristic, and this is that their slopes are opposite reciprocals. For instance, if line A has a slope of 3/4, line B which is perpendicular to line A would have a slope of -4/3. The product of the slopes of two perpendicular lines is always -1.
Perpendicular lines are commonly found in geometry and trigonometry problems. They are very useful in determining angles of triangles and shapes. For example, in a right triangle, the side opposite to the right angle is perpendicular to the hypotenuse.
Knowing that a line is perpendicular to another line can be vital in determining the position of objects in space. Perpendicular lines are also an essential part of architecture and engineering as they help in determining the placement and orientation of structures.
