A square
Explanation:
Here's the four points graphed and connected by lines:
graph{((x+2)^2+(y-3)^2-.1)((x-2)^2+(y-3)^2-.1)((x-2)^2+(y+1)^2-.1)((x+2)^2+(y+1)^2-.1)((y-0x-3)(y-0x+1)(x-0y-2)(x-0y+2))=0 [-10, 10, -5, 5]}
We have a rectangle:
- four sides
- two sets of parallel lines
- four right angles
Do we have a square? Are all the sides the same length? Yes - they are all 4 units long.
