How do i find the coodinates of the vertices?

When you want to find the coordinates of vertices on coordinate plane, first :

1- look for the movement of the vertice parallel to x-axis (how many square houses did the vertice move to left or right?)if it moved right, the number is positive. if it moved left, then it's negative.

2- find out the movement of the vertice parallel to y-axis (how many square houses did the vertice move up or down?) if it moved up, the number is positive. if it moved down, it's negative

3- write the numbers as coordinates (x,y)

for example: the coordinates of this vertice is:

it moves 4 to right(positive) and 6 to down(negative)

good luck
