This document discusses how polygons relate to vectors. Polygons can be used to add and subtract vectors using parallelogram and triangle laws. Examples show how vectors can be represented by the sides of polygons, allowing vectors to be easily visualized and understood when solving problems. Polygons are therefore closely related to the topic of vectors in physics and mathematics.

1. TOPIC 1 POLygon II

3. HOW IS RELATE TO VECTOR??? Look at this example… Example 1: P Q T S R Non-parallel vector

4. SOLUTION: Parallelogram Law Polygon is used in addition and subtraction vector to make it more understand to solve the problem. That why polygon is relate to this subtopic

5. Another example….. P Q R T S After this, you will see polygons is relate so much in the topic vector. Hope you will better understand after this.

6. SOLUTION: Triangle Law ST and SR are parallel and ST =
