In geometry, an intersection is a point, line, or curve common to two or more objects (such as lines, curves, planes, and surfaces). The simplest case in Euclidean geometry is the line–line intersection between two distinct lines, which either is one point (sometimes called a vertex) or does not exist (if the lines are parallel). Other types ...
In mathematics, the intersection of two or more objects is another object consisting of everything that is contained in all of the objects simultaneously. For example, in Euclidean geometry, when two lines in a plane are not parallel, their intersection is the point at which they meet.

The point or group of points at which two or more geometric objects cross is known as the intersection of those objects. The intersection of two sets is comprised of every number or object that both of those sets share. This can apply to numerical or non-numerical sets.
Oct 3, 2023 · Intersection of Two Lines: Given two lines in slope-intercept form: Line 1: y = m 1 x + b 1. Line 2: y = m 2 x + b 2. Set the two equations equal to each other to find the intersection point (x, y): m 1 x + b 1 = m 2 x + b 2. Solve for x: x = (b 2 - b 1 )/ (m 1 - m 2) Then, plug x into either equation to find y.
- Defining Lines. For the following exercises, use this line (Figure 10.4). Figure 10.4. Define DE¯DE¯. Define FF. Define DF↔DF↔. Define EF¯EF¯. Answer.
- Determining the Best Route. View the street map (Figure 10.7) as a series of line segments from point to point. For example, we have vertical line segments AB¯AB¯, BC¯,BC¯, and CD¯CD¯ on the right.
- Identifying Parallel and Perpendicular Lines. Identify the sets of parallel and perpendicular lines in Figure 10.10. Figure 10.10. Answer. Drawing these lines on a grid is the best way to distinguish which pairs of lines are parallel and which are perpendicular.
- Defining Union and Intersection of Sets. Use the line (Figure 10.12) for the following exercises. Draw each answer over the main drawing. Figure 10.12.
Intersection is the joining of two or more lines. An example of intersection would be when two roads meet at a corner, with one street running horizontally and the other running vertically. Another example would be when two parallel lines intersect at a single point to create an angle.
Intersecting lines are two or more lines that are coplanar to each other and meet at a common point. The three pairs of lines shown above are examples of intersecting lines. See how each pair intersects at Point $\boldsymbol {O}$? We call this the point of intersection. Line segments can also intersect and have a point of intersection.
