Question 1004550: Can you give me an example of connecting vectors that form a polygon?
How can I get the resultant vector?
My teacher said that if a vector starts at the origin and the last vector ends at the origin, it is in equilibrium.
Thank you!😃

You can put this solution on YOUR website!
You can form a square.
Start at (0,0).
First vector (1,0).
Second vector (0,1).
Third vector (-1,0).
Fourth vector (0,-1).
So when you add them all together,
(0,0)+(1,0)+(0,1)+(-1,0)+(0,-1)=(0,0)
So you get back to where you started, you closed the polygon, so the resultant vector is zero.
