First, let's draw the line PQ at point A on a piece of paper.
- Locate Point A and Draw Line PQ:
- Use a ruler to draw a straight line and mark a point A on it as the starting point.
- Label the line as PQ to represent the segment between points P and Q.
- Drawing a Perpendicular Line:
- To draw a line perpendicular to PQ at point A, place the point of the compass on point A.
- Adjust the compass width to a suitable length and draw an arc that intersects line PQ at two points.
- Without changing the width of the compass, place the point on each of the intersection points and draw two arcs intersecting each other.
- Connect the intersection points of the arcs to create a perpendicular line to PQ at point A.
- Explaining the Process:
- Drawing a perpendicular line involves creating a 90-degree angle with the given line at a specified point.
- The use of a compass ensures accuracy in locating the points where the perpendicular line intersects the given line.
By following these steps, you can draw a line PQ at a point A on a piece of paper and then draw a perpendicular line to PQ at point A with precision and accuracy.
