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.

We use learning cycles to break down learning into key concepts or ideas linked to the learning outcome. Each learning cycle features explanations with checks for understanding and practice tasks with feedback. All of this is found in our slide decks, ready for you to download and edit. The practice tasks are also available as printable worksheets and some lessons have additional materials with extra material you might need for teaching the lesson.
The assessment exit quiz will test your pupils' understanding of the key learning points.
Our video is a tool for planning, showing how other teachers might teach the lesson, offering helpful tips, modelled explanations and inspiration for your own delivery in the classroom. Plus, you can set it as homework or revision for pupils and keep their learning on track by sharing an online pupil version of this lesson.
