Coplanar

Study Guide

Key Definition

Coplanar points or lines are said to be coplanar if they lie in the same plane.

Important Notes

  • If points or lines lie in different planes, they are non-coplanar.
  • Two lines that do not intersect and are not coplanar are called skew lines.

Mathematical Notation

Standard point/plane labels (A, B, C; plane π, etc.) are sufficient.Remember to use proper notation when solving problems

Why It Works

The concept of coplanar and non-coplanar is fundamental in understanding the 3-dimensional space in geometry.

Remember

Coplanar refers to points or lines that lie in the same plane while non-coplanar refers to points or lines that lie in different planes.

Quick Reference

Coplanar:Points or lines that lie in the same plane.
