Chapter 18 Vectors and geometric proof

A vector is a quantity that has magnitude and direction. The magnitude of a vector is its size. In this section, we learn about Vectors, vector notation.

The operation to add two or more vectors together to form a vector sum is known as the addition of vectors. The addition of vectors is done in two ways, either through triangle law or parallelogram law. Where the vector subtraction is: “The addition of a vector with the negative of another vector.” In this section, we learn about Vectors, vector journeys, representing Vectors, multiply a vector by a scalar, add and subtract vectors.

Two vectors are said to be parallel if and only if the angle between them is 0 degrees. In this section, we learn about Position Vectors, Representing Vectors.

Solving geometric problems means to solve problems by using the rules of vectors. In this section, we learn about Solving Geometric Problems.
