The three main methods for adding vectors are the polygon method, the parallelogram method and vector addition using its components. Here, we will look at some examples with answers and practice problems for the topic of vector addition.
Here, you will learn state polygon law of vector addition, subtraction of vectors and multiplication of vector by scalars. Let’s begin – Polygon law of vector Addition (Addition of more than two vectors) Addition of more than two vectors is found to be by repetition of triangle law.
By the application of the law of polygon of vectors, addition of any number of vectors is possible. Suppose the resultant of four vectors \(\vec{a}\), \(\vec{b}\), \(\vec{c}\) and \(\vec{d}\) is to be determined [Fig.(a)].
How to add vectors geometrically using the nose-to-tail method or head-to-tail method or triangle method, how to add vectors using the parallelogram method, vector addition is commutative and associative, how to add vectors using components, with video lessons, examples and step-by-step solutions.

Polygon Law of Vector. According to the polygon law of vector addition, if the number of vectors can be represented in magnitude and direction by the sides of a polygon taken in the same order, then their resultant is represented by magnitude and direction such that the closing side of the polygon is taken in the opposite direction.
Here is a sample sequence of problems. This lesson is good from Grade 5 up. If you are handling different grade levels and they all reason in the same way as your fifth graders reason, you have a big problem. Problem 1. The segments in the figure below form equilateral triangles with the dotted line segment.
