Properties of Intersecting Lines 3. Non-Intersecting Lines 4. Properties of Non-Intersecting Lines 5. Intersecting Lines Examples Example 1: With respect to intersecting and non-intersecting lines, answer the following questions based on the figure given below.
Solution: According to the direction of lines, if such lines are extended further, they will meet at one point. Solution: Two examples of intersecting lines are listed below: Crossroads: When two straight roads meet at a common point they form intersecting lines.
Two examples of non-intersecting lines are listed below: Ruler scale : The opposite sides of a ruler are non-intersecting lines. Breakdown tough concepts through simple visuals. Math will no longer be a tough subject, especially when you understand the concepts through visualizations. Explore math program. Explore coding program. The point of intersection of two non- parallel lines can be found from the equations of the two lines.
Try this Drag any of the 4 points below to move the lines. Note where they intersect. Fig 1. Segments do not intersect. And, this common point that exists on all intersecting lines is called the point of intersection. The two non-parallel straight lines which are co-planar will have an intersection point. Here, lines A and B intersect at point O, which is the point of intersection. Let's consider the following case.
Evaluating the point of intersection involves solving two simultaneous linear equations. Example 1: Find the point of intersection and the angle of intersection for the following two lines:. When the lines intersect, the point of intersection is the only point that the two graphs have in common, so the coordinates of that point are the solution for the two variables used in the equations.
When the lines are parallel, there are no solutions. A necessary condition for two lines to intersect is that they are in the same plane i. They cannot intersect at only one point because planes are infinite.
Furthermore, they cannot intersect over more than one line because planes are flat.
