Primary 3 Perpendicular and Parallel Lines study guide: the whole chapter, step by step
About this subtopic
This mixed practice stop brings together 3 topics from Primary 3 Perpendicular and Parallel Lines: Name line pairs, Draw a perpendicular, Draw a parallel. Nothing on the question says which topic it comes from, so choosing the method is part of the skill.
Practice questions with worked solutions
Question 1 is free to try. The other 11 open in the free trial, each with its solution film.

For parents
How should your child approach P3 parallel and perpendicular lines mixed practice?
This page brings the Primary 3 lines subtopics together: naming line pairs, drawing a perpendicular through a point and drawing a parallel through a point.
What your child learns here
This page brings the Primary 3 lines subtopics together: naming line pairs, drawing a perpendicular through a point and drawing a parallel through a point. Nothing on a question says which kind it is, so your child must read what is asked and choose the test or the drawing steps.
- Recognising perpendicular lines by the right angle where they meet.
- Recognising parallel lines by the gap that stays the same, on a grid or by measuring.
- Naming a line pair by its letters.
- Drawing a perpendicular through a point with a ruler and a set square, and marking the right angle.
- Drawing a parallel through a point by sliding a set square along a ruler, and marking matching arrows.
Does the answer make sense?
Crossing alone does not make two lines perpendicular; only a right angle where they meet does, and parallel lines never cross at all. In every drawing here, each new line your child draws must pass through its named point and carry either a right-angle square or matching arrows to show which kind it is.
How to practise these questions
This set mixes the chapter's question types: naming line pairs, drawing perpendiculars and drawing parallels. The Basic questions keep each skill to one step, and the Intermediate questions use slanted lines and busier figures. The Challenge questions ask your child to choose the right construction from the wording and carry it out with care. When a lines question in this set stalls, view its solution film and come back to it later from Revision.
Questions parents ask
What does the P3 perpendicular and parallel lines chapter cover? The Primary 3 syllabus lists two outcomes: perpendicular and parallel lines, and drawing perpendicular and parallel lines. The pages in this chapter teach naming line pairs first, then the two drawings.
What tools does my child need for this chapter? A ruler and a set square from a school geometry set, a sharp pencil and an eraser. Squared paper helps for practice at home.
How neat do the drawings need to be? Lines should be straight, pass through the given point and be drawn with the tools, not freehand. A sharp pencil and a firm hold on the ruler make the biggest difference to accuracy.
Where can my child find perpendicular and parallel lines at home? Almost everywhere. The edges of a door meet at a right angle, the rungs of a ladder are parallel and the lines on ruled paper never meet. Ask your child to point out one pair of each in a room, and to explain how they know, using a set square to check a corner.
Do slanted lines count as perpendicular? Yes. Two lines are perpendicular when they meet at a right angle, whichever way the figure is turned. The practice includes tilted figures for this reason, so your child learns to test the angle with the set square instead of relying on lines that run straight across and straight down the page.
