What you practice

These are the CBSE Class 11 Three Dimensional Geometry skills this quiz is built around.

Plot points in three dimensions and identify octants.
Compute distance between two points in space.
Use direction cosines and ratios to describe line orientation.

A useful tip

Direction cosines satisfy l squared plus m squared plus n squared equals one, while direction ratios need not. Normalising ratios by their length converts them into cosines.
