Consecutive Interior Angles: Consecutive interior angles or co-interior angles are formed on the inside of the transversal and they are supplementary.

Alternate Exterior Angles: Alternate exterior angles are formed on either side of the transversal and they are equal in measure.

Alternate Interior Angles: Alternate interior angles are formed on the inside of two parallel lines that are intersected by a transversal.

In the given figure, there are four pairs of corresponding angles, that is, ∠a = ∠e, ∠b = ∠f, ∠c = ∠g, and ∠d = ∠h

Corresponding Angles: It should be noted that the pair of corresponding angles are equal in measure.

Given below are the pairs of angles formed by the two parallel lines L1 and L2. Each angle has been labeled using an alphabet. Eight separate angles have been formed by the two parallel lines and a transversal. Observe the following figure to see the parallel lines labeled as L1 and L2 that are cut by a transversal. While some angles are congruent (equal), the others are supplementary.

Additionally, you will also get the distance between the two lines: 3.4785Īre you interested in some of the parallel lines examples in real life? Finding parallel lines used in real-world situations is n because this math concept is undoubtedly important.When any two parallel lines are intersected by another line called a transversal, many pairs of angles are formed.

The calculator returns the new line equation: y = 3x + 9.

Enter the coordinates of a point A in the calculator.

Enter the variables (m and r) in the calculator.

How to find the equation of a parallel line and the distance between them? Scenario: You are given an equation of a line y = 3x – 2 and a point A (-2, 3) through which another line is passing. Therefore, this section will show those steps in a real example. In the previous part, you learned everything you need to know to use our calculator to find the line equations and calculate the distance between them. The calculator will return you the new line equation and the distance between them.Enter the coordinates of a point through which the second line passes – For example, A (1, 4).Enter the variables for the equation of the first line ( y = mx + r).How to find the equation of a parallel line and calculate the distance that they form: Therefore, you will learn how to calculate both using our calculator. However, if you are interested in finding it manually, head to the previous section to see the formula.īut, besides that, our calculator helps you find the equation of a line parallel to the first line you specify without problems. One of the things that our calculator calculates is the distance between two lines. You can leave all of that heavy work to our calculator and instantly get the result back to you. Note: You can easily find the distance between two lines using our calculator if you don’t want to use formulas or calculations. How to find the slope of the line m? We can calculate it with the simple equation:ĭ = \frac This direction where they are going is called the slope of parallel lines.įor example, you are given two points, A(x1, y1) and B(x2, y2), on a line m. 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. Are you interested in finding the parallel line equations and calculating the distance between two lines? If the answer is yes, check out our free online Parallel Line Calculator.īesides it, would you like to explore more of our math calculators? If yes, we have various calculators, such as Area of a Trapezoid Calculator if you need to calculate the area of a trapezoid.
