Question

If the angle between two collinear vectors is n radians, vectors are said to be ______.

Options

• antiparallel vectors

• parallel vectors

• similar vectors

• identical vectors

Answer 1

If the angle between two collinear vectors is n radians, vectors are said to be antiparallel vectors.

Explanation:

When the angle between two collinear vectors is π radians (180°), they point in exactly opposite directions along the same line, such vectors are called antiparallel vectors.
