This article provides a comprehensive guide on drawing perpendicular bisectors, which are lines that intersect a line segment at its midpoint and are perpendicular to it. To draw a perpendicular bisector, you’ll need a compass, a straight edge, and a triangle. First, mark the midpoint of the line segment with the compass. Then, place the compass at the midpoint and draw two arcs to intersect the line segment on either side of the midpoint. Lastly, draw a straight line through the two intersection points to form the perpendicular bisector.

Concepts Related to Drawing Perpendicular Bisectors
Before delving into the step-by-step instructions for drawing perpendicular bisectors, it’s essential to establish a common understanding of some key terms.
- Congruent: Two figures or segments that have the same shape and size.
- Triangle: A polygon with three straight sides and three angles.
- Perpendicular: Lines or planes that form right angles (90 degrees) when they intersect.
- Bisector: A line, ray, or segment that divides a shape or angle into two equal parts.
- Compass: A drawing tool used to draw circles and arcs.
- Straight edge: A ruler or similar tool used to draw straight lines.
- Compass bisect: Using a compass to locate the midpoint of a line segment.
Step-by-Step Guide to Drawing Perpendicular Bisectors
In geometry, a perpendicular bisector is a line that passes through the midpoint of a line segment and is perpendicular to it. Drawing perpendicular bisectors is a fundamental skill in geometry and has various applications in real-life scenarios.
To draw a perpendicular bisector using a compass and a straight edge, follow these step-by-step instructions:
Step 1: Find the Midpoint of the Line Segment
- Place the compass at one endpoint of the line segment and extend the compass to the other endpoint.
- Without changing the compass width, make two small arcs above and below the line segment, intersecting the line segment at points A and B.
- Connect points A and B with a straight edge. This line represents the perpendicular bisector of the line segment.
Step 2: Verify the Perpendicularity
- Place the compass at the midpoint of the line segment.
- Extend the compass to point A on the perpendicular bisector.
- Without changing the compass width, draw an arc that intersects the perpendicular bisector at point D.
- Repeat the same process to draw an arc that intersects the perpendicular bisector at point E.
- If points D and E coincide, then the line through A and B is perpendicular to the line segment.
Step 3: Extend the Perpendicular Bisector
- Extend the line through A and B to both sides of the line segment.
- This extended line represents the perpendicular bisector of the line segment, which divides the line segment into two congruent halves.
