Geometry (P5) Practice
Master properties of triangles (equilateral, isosceles, right-angled), quadrilaterals (parallelogram, rhombus, trapezium), and calculate unknown angles using angle properties and parallel line rules.
Common Mistakes to Avoid
Confusing the properties of rhombus vs parallelogram
Missing angles at a point (must sum to 360°) or on a straight line (180°)
Incorrectly applying 'angles in a triangle sum to 180°' to quadrilaterals
Practice Questions
Try each question. When you're stuck, reveal the Socratic strategy — a guided hint that teaches you how to think, not just what to write.
In a triangle PQR, angle P = 47° and angle Q = 68°. Find angle R.
ABCD is a parallelogram. Angle A = 115°. Find angles B, C, and D.
A rhombus has one angle of 70°. What are the other three angles?
Parent & Tutor Insight
Geometry questions reward students who know their properties cold. Make a simple reference card of each shape and its angle/side properties — students who memorise these spend less time reconstructing them under exam pressure.

Common Questions
What shape properties must my P5 child know for exams?
Triangles: equilateral (3 equal sides/angles), isosceles (2 equal), scalene (all different), right-angled. Quadrilaterals: square, rectangle, parallelogram, rhombus, trapezium. For each, know: which sides are equal, which angles are equal, whether diagonals bisect.
Are parallel lines tested at P5?
Yes — the P5 syllabus introduces alternate angles and corresponding angles formed by parallel lines cut by a transversal. These are often embedded in geometry problems without explicitly labelling the parallel lines.
