 Which Diagram Below Shows the First Step in Parallel Line Construction on a Point Outside a Line?

When it comes to parallel line construction, understanding the steps involved is crucial. One of the first steps in constructing a parallel line involves using a point outside the line. Let’s take a look at the diagram below to identify which one shows this initial step.

The correct answer is diagram [A/B/C/D].

To construct a parallel line on a point outside the line, follow these steps:

1. Begin by drawing a line and label it as line AB.
2. Choose a point outside line AB and label it as point P.
3. Draw a line segment from point P that intersects line AB at point Q.
4. Place the compass at point Q and adjust its width to reach point P.
5. Without adjusting the compass, place it at point P and draw an arc that intersects line AB at two points, R and S.
6. Draw a line segment connecting points R and S.
7. The line segment RS is parallel to line AB.

1. Why is it important to construct parallel lines?
Constructing parallel lines is important in various mathematical and practical applications, such as geometry, engineering, and architecture.

2. Can a parallel line be constructed on a point inside the line?
No, a parallel line cannot be constructed on a point inside the line. It requires a point outside the line.

3. What is the purpose of using a compass in parallel line construction?
The compass helps in accurately measuring and duplicating distances and angles, ensuring the construction of parallel lines.

4. Is it possible to construct multiple parallel lines on a single point outside a line?
No, only one parallel line can be constructed on a single point outside a line.

5. Are parallel lines always equidistant from each other?
Yes, parallel lines are always equidistant from each other, meaning the distance between them remains constant.

6. Can parallel lines intersect?
No, parallel lines never intersect. They remain equidistant and run indefinitely in the same direction.
