Help your students prepare for their Maths GCSE with this free perpendicular bisector worksheet of 30+ questions and answers
The perpendicular bisector of a line segment AB is a line, at right angles to the segment, which goes through the midpoint of the segment, cutting it in half (bisects it). To bisect a line segment, you will need a pencil, a pair of compasses and a straight edge (ruler).
There is a set method to construct perpendicular bisectors of line segments. First, place the point of the compasses on one endpoint of the line segment. With the compasses open to over half the length of the line, draw an arc. Next, move the point of the compasses to the other endpoint of the line and, without changing the angle of the compasses, draw another arc. Finally draw a straight line between the two intersections of the arcs.
It is important to note that a protractor is not used to draw a perpendicular bisector.
Looking forward, students can then progress to additional loci and construction worksheets and other geometry worksheets, for example an angles in polygons worksheet or area and circumference of a circle worksheet.
There will be students in your class who require individual attention to help them succeed in their maths GCSEs. In a class of 30, it’s not always easy to provide.
Help your students feel confident with exam-style questions and the strategies they’ll need to answer them correctly with our dedicated GCSE maths revision programme.
Lessons are selected to provide support where each student needs it most, and specially-trained GCSE maths tutors adapt the pitch and pace of each lesson. This ensures a personalised revision programme that raises grades and boosts confidence.
