Checking and securing understanding of constructing the perpendicular bisector of a line segment
I can use the properties of a rhombus to construct a perpendicular bisector of a line segment.
Checking and securing understanding of constructing the perpendicular bisector of a line segment
I can use the properties of a rhombus to construct a perpendicular bisector of a line segment.
These resources will be removed by end of Summer Term 2025.
Lesson details
Key learning points
- A rhombus can be constructed from two congruent isosceles triangles
- The diagonals of a rhombus meet at right angles and bisect each other
- It is possible to construct the perpendicular bisector of a line segment without drawing the rhombus
- The line segment could be part of a shape
Keywords
Bisect - To bisect means to cut or divide an object into two equal parts.
Perpendicular - Two lines are perpendicular if they meet at right angles.
Rhombus - A rhombus is a parallelogram where all sides are the same length.
Common misconception
"My construction didn't accurately bisect the line segment"
Check that your compasses construct a full circle, and do not slip (and create a spiral-shape). Tighten the screw on your compasses, if possible. Then, if only using construction arcs that look confusing, you can construct full circles to help.
Equipment
Pair of compasses, ruler.
