What is a directed line segment or vector

The video tutorial introduces vectors and directional line segments, explaining how they are defined by initial and terminal points, such as P and Q. It emphasizes the importance of direction and distance in defining these segments and introduces the concept of vectors as directional line segments on a plane. The tutorial also covers vector notation, using lowercase letters like V, U, and W, and explains vector equivalence based on having the same direction and magnitude.

What are the initial and terminal points in a line segment?

• P is the terminal point and Q is the initial point

• P is the initial point and Q is the terminal point

• Both P and Q are terminal points

• Both P and Q are initial points

Why is the direction important in a directional line segment?

• It determines the length of the line segment

• It indicates the starting and ending points

• It shows the path from Q to P

• It is irrelevant in defining a line segment

What is a vector commonly referred to in a plane?

• An angle

• A directional line segment

• A point

• A line

How are vectors typically represented?

• Using symbols

• Using numbers

• Using lowercase letters

• Using uppercase letters

Under what conditions are vectors considered equal?

• When they have the same initial point

• When they have the same terminal point

• When they have the same direction and magnitude

• When they are parallel
