To find the coordinates of each point, we look at where the point lines up with the numbers on the horizontal axis (the x-axis) and the vertical axis (the y-axis). The format for writing coordinates is always $(x, y)$.
Here is the step-by-step breakdown for each point:
Point A:
* Go left from the center to
-5.
* Go up to
2.
* Coordinate:
(-5, 2)
Point B:
* Go right from the center to
2.
* Go up to
2.
* Coordinate:
(2, 2)
Point C:
* Go right from the center to
4.
* Go up to
2.
* Coordinate:
(4, 2)
Point D:
* Go right from the center to
2.
* This point is on the horizontal line, so the height is
0.
* Coordinate:
(2, 0)
Point E:
* Go right from the center to
3.
* Go down to
-4.
* Coordinate:
(3, -4)
Point F:
* Go left from the center to
-2.
* Go up to
2.
* Coordinate:
(-2, 2)
Point G:
* Go left from the center to
-4.
* Go down to
-3.
* Coordinate:
(-4, -3)
Point H:
* Go left from the center to
-2.
* This point is on the horizontal line, so the height is
0.
* Coordinate:
(-2, 0)
Point I:
* This point is right in the middle where the lines cross. The value is
0 for both.
* Coordinate:
(0, 0)
Point J:
* This point is on the vertical line in the middle, so the side-to-side value is
0.
* Go down to
-2.
* Coordinate:
(0, -2)

What shape have you just drawn?
If you connect the points in order from A to J and then back to A, the shape has 10 sides. In geometry, a 10-sided polygon is called a
decagon. Because the sides are different lengths, it is an irregular decagon.
Final Answer:
Coordinates:
A. (-5, 2)
B. (2, 2)
C. (4, 2)
D. (2, 0)
E. (3, -4)
F. (-2, 2)
G. (-4, -3)
H. (-2, 0)
I. (0, 0)
J. (0, -2)
Shape: Decagon
