GCSE Mathematics · key term
A flat surface that extends indefinitely in every direction within it.
Used by AQA, Edexcel and OCR
Specification G1 · Paper 1, Paper 2, Paper 3
A flat two-dimensional surface that extends without end in every direction within it.
Revise: Geometric Notation: Points, Lines and PlanesA plane is a perfectly flat surface extending without end in all directions within that surface. A sheet of paper suggests part of a plane, but the mathematical plane has no boundary or thickness. Points and lines lying in one plane are coplanar.

A flat surface extending indefinitely.
Revise: Geometric Terms and NotationsA plane is a flat surface extending indefinitely; diagrams of triangles and other flat shapes are usually drawn in one plane.
A flat two-dimensional surface that extends in all directions; a face of a solid can lie in a plane.

Revise: Shape TerminologyA plane is a perfectly flat surface extending indefinitely. A sheet of paper gives you a way to picture a small part of one. Points, lines and segments can all lie in the same plane.
In a 3D diagram, lines that never meet are not necessarily parallel: they must also lie in the same plane.
Check that the angle used is actually inside the right-angled triangle you have drawn. For a line–plane angle, use the line and its perpendicular projection onto the plane.
In a 3D diagram, lines that appear not to meet are not necessarily parallel: they must lie in the same plane.
