What are perpendicular lines?

Perpendicular lines are two lines that intersect at a 90-degree angle, forming a right angle. This means that the lines lie in different planes and do not coincide with each other, but instead cross each other at a right angle. Perpendicular lines are crucial in geometry and have specific properties and relationships that make them well-defined and distinguishable from other types of lines.

How are perpendicular lines different from parallel lines?

Perpendicular lines intersect at a 90-degree angle, creating right angles where they cross, while parallel lines never intersect and remain equidistant from each other. Perpendicular lines can be found in the shape of an "L" or forming the corners of rectangles, while parallel lines run alongside each other indefinitely without ever meeting.

How can you determine if two lines are perpendicular?

Two lines are perpendicular if the product of their slopes is -1. In other words, if line 1 has a slope of m1 and line 2 has a slope of m2, the lines are perpendicular if m1 * m2 = -1. This fundamental relationship helps determine if two lines intersect at a right angle, defining perpendicularity.

Can two perpendicular lines intersect?

No, two perpendicular lines do not intersect. Perpendicular lines are two lines that meet at a right angle, forming a 90-degree angle between them. As a result, they are always parallel and never cross each other.

What is the angle formed when two lines are perpendicular?

When two lines are perpendicular to each other, they form a 90-degree angle.

How many perpendicular lines can be drawn through a given point on a line?

Only one perpendicular line can be drawn through a given point on a line. This is a fundamental property of geometry where a unique line can be drawn at a right angle to another line passing through a specific point.

Can a line be perpendicular to itself?

No, a line cannot be perpendicular to itself. Perpendicular lines are two lines that intersect at a right angle of 90 degrees, and by definition, they must be distinct and not the same line.

Are perpendicular lines always the same length?

Perpendicular lines are not always the same length. Perpendicular lines meet at a 90-degree angle, but they can vary in length. The length of the lines depends on their placement and orientation in space. Two perpendicular lines could have different lengths based on how they are positioned relative to each other.

Can two lines be perpendicular if they are not straight lines?

No, two lines cannot be perpendicular if they are not straight lines. Perpendicular lines are lines that intersect at a right angle, which is only possible for straight lines.

In a right-angled triangle, how are the sides related to the perpendicular lines drawn from the right angle?

In a right-angled triangle, the sides are related to the perpendicular lines drawn from the right angle as follows: the perpendicular line drawn from the right angle to the hypotenuse divides the hypotenuse into two segments, which are proportional to the two other sides of the triangle. This relationship is known as the geometric mean theorem.
