Parallelogram, Rhombus and Trapezium
Read the arrows and ticks on a four-sided figure, then name it and state the properties that follow.
Your child learns to read the marks on a four-sided figure: matching arrowheads for parallel sides and ticks for equal sides. From the marks, your child names the shape as a parallelogram, rhombus or trapezium and uses what is true of it to find a length or an unknown angle, then completes such figures on a grid by counting squares.

About this chapter
Primary 5 parallelogram, rhombus and trapezium questions read the arrowheads and ticks on a quadrilateral, name the shape, and use its properties. The chapter covers the properties of all three shapes and finding unknown angles in them.
Practise by question type: p5 quadrilateral properties questions, p5 parallelogram angle questions and p5 drawing shapes on a grid questions.
The order to learn them
The building blocks
12.1
Which sides are equal or parallel?
12.2
Drawing the missing sides
12.3
The number tells you where a question type sits in this chapter, not what your child needs to learn first. A child who has already met a type in school can practise it without working through the ones above it.
How the end-of-year papers set these questions
Modelled against the Primary 5 end-of-year papers
We write the questions ourselves. This chapter is modelled on the types of question set in the 2025 Primary 5 end-of-year papers.
These figures appear in Paper 1 and Paper 2
A question may ask for an unknown angle or for a figure to be completed on a grid. Longer questions may place a triangle on a parallelogram, rhombus or trapezium and use more than one property.
The side marks determine the method
Arrow marks state which sides are parallel, and tick marks state which sides are equal. Practice questions are not labelled by type, so children must read those marks before choosing a method.
Everything here is modelled against top school papers. Those papers are never reproduced, and every question on this site is original.
How to set out the working clearly
These examples show Mathweave's clear, consistent layout for each method. The layout is informed by the answer keys we reviewed.
- Read the arrow marks before choosing a property A parallelogram and a rhombus have two pairs of parallel sides. A trapezium has one pair. The arrows on the figure show which pair is meant.
- Write the reason beside each angle equation Name the angle, show the calculation and put the property in brackets on the same line.
- Choose the correct pair of angles Opposite angles in a parallelogram or rhombus are equal. The two angles between a pair of parallel sides add to 180°.
- Count both the run and the rise on a grid To copy a slanted side, count its horizontal and vertical steps. Repeat both counts for a parallel side and check the completed figure against every given mark.
Questions parents ask
Is this on the Primary 5 syllabus?
Yes. The chapter follows the Parallelogram, Rhombus and Trapezium outcomes in the latest MOE Primary Mathematics syllabus.
Which practice is available now?
All three question types have original practice. The angle and grid lessons are also shared with Primary 6.
Why do two lessons also appear in Primary 6?
Finding angles in four-sided figures and drawing on a grid are used at both levels. Each question type has one lesson page with the level line Primary 5 and Primary 6.
Are the questions from past papers?
We write the questions ourselves rather than copy them from papers. Each chapter is modelled on the types of question that top school papers set. A question may look like one your child has met before because it is the same type.
What does the practice add over the films?
Practice uses different numbers for each question type, shows the working after every attempt and records which types your child can complete independently.
