Which lines intersect

There are some lines that intersect each other but may not be necessarily perpendicular to each other. When any two lines meet at one common point, they are called intersecting lines. The common point where they intersect is known as the point of intersection. Learn Practice Download. Intersecting Lines In geometry, when two or more lines meet or cross each other in a plane, they are termed as intersecting lines. What Are Intersecting Lines 2. 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. That point would be on each of these lines. In Figure 1 , lines l and m intersect at Q. Figure 1 Intersecting lines.

Two lines that intersect and form right angles are called perpendicular lines. Figure 2 Perpendicular lines. Two lines, both in the same plane, that never intersect are called parallel lines.

In Fig 1 we see two line segments that do not overlap and so have no point of intersection. However, if you apply the method above to them, you will find the point where they would have intersected if extended enough. In the interest of clarity in the applet above, the coordinates are rounded off to integers and the lengths rounded to one decimal place.

This can cause calculatioons to be slightly off. Home Contact About Subject Index.
