GCSE Mathematics · key term
A solid with two congruent, parallel polygonal ends and the same cross-section throughout its length.
Used by AQA, Edexcel and OCR
Specification G12 · Paper 1, Paper 2, Paper 3
Revise: 3D ShapesA prism has two congruent, parallel polygonal ends. Corresponding vertices on these ends are joined, and its cross-section stays the same shape and size along its length. A prism is named after the polygon at its ends: a triangular prism has triangular ends, while a pentagonal prism has pentagonal ends.
Specification G12, G16 · Paper 1, Paper 2, Paper 3
A 3D shape with two congruent, parallel polygonal end faces and a constant polygonal cross-section.
Revise: 3D Shape PropertiesA prism has the same polygonal cross-section all the way along its length. Its two end faces are congruent and parallel, and corresponding vertices are joined by side faces. The prism is named after its cross-section: for example, a triangular prism has triangular ends.
A three-dimensional solid with the same cross-section throughout its length.
Specification 8.01d, 8.06a · Paper 1 (Foundation), Paper 2 (Foundation), Paper 3 (Foundation), Paper 4 (Higher), Paper 5 (Higher), Paper 6 (Higher)
A polyhedron with two matching, parallel polygonal ends and the same cross-section throughout its length.
Revise: Solid TerminologyA prism has two matching, parallel polygonal ends. Between them, its cross-section stays the same. A cross-section is the flat shape revealed by a slice through a solid.
A three-dimensional solid with two identical, parallel polygonal ends and the same cross-section throughout its length.
For a prism or pyramid, first count the sides of its end face or base. Then use the appropriate counting pattern.
For a prism or pyramid, identify the polygon at the end or base and count its sides as before using a rule.
For a prism, calculate the area of one constant cross-section first, then multiply by the perpendicular length of the prism.
