Free P5 Maths paper: Angles in triangles and quadrilaterals
A full Paper 1 and Paper 2 at the level of a hard P5 end-of-year paper, in the PSLE format, for Singapore P5 pupils. 29 of the 100 marks are on angles in triangles and quadrilaterals; the rest cover the other P5 topics, as a real paper does.
Free. No sign-up to start. Untimed, like homework, and your answers save as you type. Paper 2 follows Paper 1. The score shows the moment Paper 2 is handed in, and a parent can unlock the full diagnosis and have it emailed.
What is in the paper

The focus: 29 marks on angles in triangles and quadrilaterals, across both papers, from one-mark multiple choice to a five-mark final question. Also in the paper: Whole numbers, Area and perimeter, Fractions, Percentage, Volume, Rate, Measurement, Data tables and graphs, Decimals.
Timing is up to you. Sit it in one go against the PSLE times for exam practice, or spread it over a few evenings as class homework is.
Where the marks go in angles and geometry
Angles in P5 papers come as figures: an isosceles triangle whose given angle may be the top angle or a base angle, a parallelogram or trapezium whose next-door angles add up to 180°, and a rhombus or trapezium cut by a diagonal. The step that is never stated is usually a pair of equal sides.
The mistakes this paper looks for
- Missing two equal sides because they are sides of the same rhombus or triangle
- Assuming the given angle of an isosceles triangle is a base angle
- Treating a parallelogram's angles as if it were a rectangle
Try a question from this paper
Paper 1, Question 13 (2 marks). ABCD is a rhombus and BD is a straight line joining B and D. ∠ABD = 43°. Find ∠BCD.
- 86°
- 137°
- 94°
- 47°
Show the answer
(3) 94°
A diagonal of a rhombus cuts its angles in half.
∠ABC = 2 × 43° = 86°
∠BCD = 180° − 86° = 94° (angles next to each other add up to 180°)
