Year 9 Constructions Worksheets | Printable PDFs
Year 9 Constructions worksheets for Year 9 Maths (Key Stage 3). Students aged 13–14 learn how to construct triangles, draw accurate diagrams and sketch shapes using mathematical notation. Below, students practise drawing regular polygons, using bisectors and complete more challenging construction activities.
Students in year 9 must be able to use a protractor and straight edge to construct perpendicular bisectors and angle bisectors. A perpendicular bisector is a line that cuts another line exactly in half at a right angle (90°). An angle bisector is a line that divides an angle into two equal angles. For questions on Loci, a topic which often follows constructions, see Year 9 Loci Worksheets.

Common Questions about Year 9 Constructions
What equipment is needed for accurate geometric constructions?
A ruler, compass and pencil are used to produce accurate constructions.Why are arcs used when constructing shapes?
Arcs allow precise distances and positions to be marked, helping to locate points accurately without measuring.Why should construction lines be left visible?
Construction lines show the method used and provide evidence that the shape has been constructed accurately.
Year 9 Constructions Common Mistakes
Common Mistake 1
Rubbing out construction lines instead of leaving them visible.Common Mistake 2
Using a ruler to guess distances instead of using compass arcs accurately.Common Mistake 3
Not keeping the compass width the same when copying lengths or drawing arcs.
