Corresponding angles in parallel lines are equalĪ parallel line never intersect with another therefore, they are pointing in an infinite direction.

Vertically opposite angles of two parallel lines are equal.

In other words, they always have these properties:

PropertiesĪccording to the parallel lines definition in math, we conclude that each of them share the same properties.

We find them useful mainly in understanding the relationships between the paths of objects and sides of various shapes. So, for example, AC || DE denotes that the line AC is alongside to the line DE. If two lines are parallel, then we use the symbol || to represent their relationship. Therefore, parallel lines are central and always form the same slope. Additionally, no matter how much you extend them, they will never meet. In geometry, we define them as two lines located in the same plane (flat surface) at an equal distance from each other. What are parallel lines in math, or more specifically in geometry? Also, there is our Cross Product Calculator for calculating the product of vectors. This can be expressed mathematically as \(m_1 × m_2 = -1\), where \(m_1\) and \(m_2\) are the slopes of two lines that are perpendicular.Are you interested in finding the parallel line equations and calculating the distance between two lines?

If yes, we have various calculators, such as Area of a Trapezoid Calculator if you need to calculate the area of a trapezoid. The slope of one line is the negative reciprocal of the other line. Perpendicular lines do not have the same slope. Mathematically, this can be expressed as \(m_1= m_2\), where \(m_1\) and \(m_2\) are the slopes of two lines that are parallel. For example, if the equations of two lines are given as, \(y=-2x + 6\) and \(y=-2x – 4\), we can see that the slope of both the lines is the same \((-2)\). Since two parallel lines never intersect and have the same slope, their slope is always equal. Here \(a\) represents the slope of the line. The equation of a straight line is represented as \(y=ax+b\) which defines the slope and the \(y\)-intercept.

All perpendicular lines can be called intersecting lines, but not all intersecting lines can be called perpendicular because they must intersect at right angles.Įquations of parallel and perpendicular lines.

Perpendicular lines always intersect at \(90°\).

Parallel lines are always equidistant from each other.

For example, \(PQ ⊥ RS\) means line \(PQ\) is perpendicular to line \(RS\). Perpendicular lines are denoted by the symbol \(⊥\). On the other hand, when two lines intersect at a \(90\)-degree angle, they are known as perpendicular lines. For example, \(AB || DF\) means line \(AB\) is parallel to line \(DF\). The symbol \(||\) is used to represent parallel lines. They are always the same distance apart and are equidistant lines. If two straight lines are on the same plane and if they never intersect, they are called parallel lines. Step by step guide to parallel and perpendicular lines
