A group of lines are further classified into two types based on the nature of the intersection between these lines.<\/span><\/p>\n
- \n
- Intersecting lines<\/b><\/li>\n<\/ul>\n
- \n
- Parallel lines\u00a0<\/b><\/li>\n<\/ul>\n
Two intersecting lines can be <\/span>perpendicular lines<\/b> when the angle between them is equal to 90 degrees.<\/span><\/p>\n
<\/span><\/p>\n
Based on the inclination, lines are classified into two types:\u00a0<\/span><\/p>\n
- \n
- Horizontal line<\/b><\/li>\n<\/ul>\n
- \n
- Vertical line<\/b><\/li>\n<\/ul>\n
<\/span><\/p>\n
We will now read about these lines mentioned above in detail.<\/span><\/p>\n

Straight Line<\/b><\/b><\/h2>\n
- \n
- A straight line is a combination of many points along a straight path having no end in both directions.\u00a0<\/span><\/li>\n
- Its length is indefinite.<\/span><\/li>\n
- It has zero width and hence is a one-dimensional figure.<\/span><\/li>\n
- In the figure shown below, the arrow on both sides indicates that the straight line extends indefinitely in both directions.<\/span><\/li>\n<\/ul>\n

Line segment\u00a0<\/b><\/h2>\n
- \n
- A line segment is a part of the straight line having two fixed ends.<\/span><\/li>\n
- Its length is definite.<\/span><\/li>\n
- It has zero width.<\/span><\/li>\n
- In the figure shown below, AB is a line segment having two endpoints A and B.<\/span><\/li>\n<\/ul>\n

<\/b><\/h2>\n\u00a0<\/span><\/p>\n
Ray\u00a0<\/b><\/h2>\n
- \n
- A ray is a part of the straight line having only one endpoint and extending infinitely in the other direction.<\/span><\/li>\n
- Its length is not definite.<\/span><\/li>\n
- It has zero width.<\/span><\/li>\n
- In the figure given below, the arrow on one side indicates that the ray extends indefinitely in one direction.<\/span><\/li>\n<\/ul>\n

<\/b><\/h2>\n<\/p>\n
Intersecting lines<\/b><\/h2>\n
- \n
- When there exists a point that lies on both the lines, then these lines are termed as intersecting.<\/span><\/li>\n
- In the figure given below, point P lies on both lines. In other words at this point, both lines meet each other. P is also known as the point of intersection in this case.<\/span><\/li>\n<\/ul>\n

<\/b><\/h2>\n<\/p>\n
Parallel Lines<\/b><\/h2>\n
- \n
- The lines that can never meet each other even are known as parallel lines.<\/span><\/li>\n
- In other words, there is no common point present on both lines.<\/span><\/li>\n
- The distance between two parallel lines is constant throughout the lines.<\/span><\/li>\n
- In the figure given below, lines AB and PQ are parallel to each other.<\/span><\/li>\n<\/ul>\n

<\/b><\/h2>\n<\/p>\n
Perpendicular lines<\/b><\/h2>\n
- \n
- When two lines intersect each other such that the angle between them is equal to 90\u00b0, then these are known as perpendicular lines.<\/span><\/li>\n
- In the figure given below, the angle between line AB and PQ is 90\u00b0.<\/span><\/li>\n<\/ul>\n

<\/b><\/h2>\n<\/span><\/p>\n
Horizontal Line<\/b><\/h2>\n
The line parallel to the x-axis is termed the horizontal line. They span from left to right. Horizontal lines are perpendicular to vertical lines.<\/span><\/p>\n
In the figure given above AB is a horizontal line.<\/span><\/p>\n
<\/span><\/p>\n
Vertical Line<\/b><\/h2>\n
The line parallel to the y axis is termed the vertical line. They span from bottom to top. Vertical lines are perpendicular to horizontal lines.<\/span><\/p>\n
In the figure given above PQ is a vertical line.<\/span><\/p>\n
