Question

Which best describes the polygon whose vertices in the coordinate plane are (-2, 3), (2, 3), (2, -1), (-2, -1)?

Answer 1

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.
