Parallel, Perpendicular, and Intersecting Lines

Kinds of Lines

• Horizontal Lines , Lines mapped from left-to-right or right-to-left and which are parallel to the (x)-axis in a plane are known as horizontal lines.
• Vertical Lines , Lines mapped from up to down or down to up and are parallel to the (y)-axis in a plane are known as vertical lines.
• Intersecting Lines, Whenever (2) lines cross one another and meet up at a point, they’re called intersecting lines. The point where they meet up is called the point of intersection.

 Intersecting Lines Properties

• Intersecting lines link at a single point, and they can’t meet up at more than a single point.
• Intersecting lines meet up with one another at any angle that’s bigger than (0°) and lower than (180°).

• Perpendicular Lines, Whenever (2) lines intersect precisely at (90°), they’re called perpendicular lines.
• Parallel Lines, (2) lines are understood to be parallel if they don’t intersect at any point as well and they are equidistant.

Non-intersecting Lines Properties

• Non-intersecting lines don’t ever meet up, and they don’t share any kind of common point. They’re additionally called parallel lines.
• The gap in-between non-intersecting lines is constantly equal.
• The size of any common perpendicular drawn between the (2) non-intersecting lines is constantly equal.

Hints on Points and Lines

• Whenever (2) distinct points are linked, they create a line.
• A line goes in two directions forever.
• Parallel lines don’t intersect one another.
• The line that intersects at (90°) are called perpendicular lines.
• (2) or more points that lie on one straight line are called collinear points.

Parallel, Perpendicular, and Intersecting Lines, Example 1:

These two lines cross each other and intersect at (90°), so they are both intersecting and perpendicular to each other.

Parallel, Perpendicular, and Intersecting Lines, Example 2:

State whether the given pair of lines is parallel, perpendicular, or intersecting.

Solution:

These two lines do not intersect at any point so they are parallel.
