Introduction

In geometry, drawing a line perpendicular to a given line is an essential skill that requires precision and accuracy. This can be achieved using simple tools like compasses and a ruler. In this article, we will guide you through the step-by-step process of drawing a line perpendicular to a given line using compasses and a ruler.

Understanding the Basics

Before we dive into the construction process, it's essential to understand the basics of geometry and the tools used. A compass is a circular drawing tool with two points, one fixed and the other movable. The fixed point is called the pivot, and the movable point is called the point. A ruler is a straightedge used for drawing straight lines.

Step-by-Step Construction

While the title of the question does not require the step-by-step construction, we will still provide a general overview of the process for clarity.

Draw a line AB: Start by drawing a line AB on a piece of paper using a ruler.
Take a point P outside line AB: Take a point P outside line AB. This point will be used as a reference point for drawing the perpendicular line.
Draw a line through P and perpendicular to AB: Using a compass, draw a line through point P and perpendicular to line AB. This can be achieved by placing the point of the compass on point P and adjusting the compass to draw a circle with a radius equal to the distance between point P and line AB. Then, place the point of the compass on the intersection of the circle and line AB, and adjust the compass to draw a line through point P and perpendicular to line AB.

Drawing a Line Perpendicular to a Given Line Using Compasses and Ruler

Now that we have covered the basics and the step-by-step process, let's dive into the actual construction process.

Drawing a Circle with a Given Radius

To draw a line perpendicular to a given line using compasses and a ruler, we need to draw a circle with a given radius. This can be achieved by placing the point of the compass on the given point and adjusting the compass to draw a circle with a radius equal to the distance between the given point and the line.

Drawing a Line through the Center of the Circle and Perpendicular to the Line

Once we have drawn the circle, we need to draw a line through the center of the circle and perpendicular to the line. This can be achieved by placing the point of the compass on the center of the circle and adjusting the compass to draw a line through the center of the circle and perpendicular to the line.

Drawing a Line through the Point and Perpendicular to the Line

Finally, we need to draw a line through the point and perpendicular to the line. This can be achieved by placing the point of the compass on the point and adjusting the compass to draw a line through the point and perpendicular to the line.
