If the vertices A, B, C of a triangle ABC are the points with position vectors respectively, what are the vectors determined by its sides? Find the length of these vectors.

Let the position vector of the vertex ‘A’ is ,

And similarly B and C

Side AB is

………..(1)

Equation (1) vector representation of the side AB

Magnitude of side AB,

And similarly for side BC and CA

……….(2)

Length of side BC and CA
