2.What are equal vectors?

1. Any straight line segment in a plane is defined by the two its endpoints. A straight line segment in a plane become the directed straight line segment when one of its two endpoints is declared as the initial point while the other endpoint is declared as the terminal point.

2. Two vectors AB and CD in a plane are called equal (or equivalent), AB=CD, if the segments AB and CD are parallel and co-directed, and have equal length.

For vectors see my lesson in this site Vectors in a plane.
