Course review
Review each learning objective in this topic, then open its concept explanation or question set.
Learning objective
• Use distance and midpoint in three-dimensional space. • Use volume and surface area of 3D solids and combinations. • Identify right-angled triangles in 3D objects to find lengths and angles.
Start with the concept explanation, then practise to create mastery evidence.
Learning objective
• Use sine, cosine and tangent in right-angled triangles. • Use sine rule, cosine rule and area formula 1/2 ab sin C. • Ambiguous sine-rule case is not included at SL.

Learning objective
• Use sites, vertices, edges and cells in Voronoi diagrams. • Add a site, use nearest-neighbour interpolation and solve toxic-waste-dump style problems. • Find boundaries, closest sites and region areas; applications include planning, disease, ecology and meteorology.
