Intersecting lines
Intersecting lines are two lines that cross or meet each other at a single point. This point is called the point of intersection. When two lines intersect, they share exactly one point in common.
Intersecting lines can be represented by the symbol "⦢". The point where the lines meet is denoted by a small dot. This dot represents the common solution or point of intersection between the two lines.
Intersecting lines can have different angles formed at the point of intersection. The angles can be acute (less than 90 degrees), obtuse (greater than 90 degrees), or right angles (exactly 90 degrees). The angles formed by intersecting lines depend on the measures of the angles of the lines themselves.
For example, if two intersecting lines form four angles, and one of those angles is a right angle, then the lines are said to be perpendicular. Perpendicular lines have a special property in that the angle between them is always 90 degrees.
It is important to note that intersecting lines can intersect at any angle, and they can also be parallel to each other. However, parallel lines do not intersect at all, which means they do not share any common points.
In summary, when two lines have only one point in common, they are called intersecting lines. This point of intersection is the only point that these lines share. It is different from parallel lines which do not intersect at all.
