Year 7 Mathematics
Triangles and Angles
Three timed mock papers covering angle relationships, parallel lines, triangles, and quadrilaterals. Every question is scaffolded into small steps — you’re never expected to figure out a whole answer in one go.
⚹ How the Trials Work
Each trial is a full mock examination. Every question is broken into small parts (a), (b), (c)… and each part has its own box for your answer. When you type an answer and press Check, you will see straight away whether it is right. If it is wrong, you get a hint — then you can try again.
The timer counts down. You can submit whenever you are ready, or it will submit on its own when the time runs out. At the end, you will see your score with a topic breakdown and full worked solutions for every question.
The trials grow in difficulty. Trials A and B are a fair test of what you have learned. The Achievement Standard (Trial C) is harder — you will need to put several ideas together — but every step is still scaffolded so you can work it out piece by piece.
Trial A
30 min · 30 marks
Year 7 Semester Practice A
Complementary and supplementary angles, angles at a point, vertically opposite, parallel-line angles, triangle angle sum, isosceles triangles. Heavily scaffolded.
Trial B
30 min · 30 marks
Year 7 Semester Practice B
Fresh angle-relationship problems, parallel lines, exterior angle of a triangle, quadrilateral angle sum, isosceles triangles.
Trial C
45 min · 45 marks
The Achievement Standard
Five multi-step problems: a full parallel-line angle chase, an algebraic triangle (solve for x using the triangle sum), a quadrilateral with two equal angles, isosceles with exterior angle theorem, and a pentagon with a line of symmetry.
