Question

If the coordinates of polygon graphed in the first quadrant with one vertex on the origin are (0,0), (a,0), (a,a), (0,a), then what is the most precise name for the polygon.

Answer 1

Square

Explanation:

It is given that the coordinates of polygon graphed in the first quadrant with one vertex on the origin are (0,0), (a,0), (a,a), (0,a).

Let A=(0,0),

B=9(a,0),

C=(a,a) and

D=(0,a)

Then, using the distance formula, we have

`AB=√((a-0)^2+(0-0)^2)=a`,

`BC=√((a-a)^2+(a-0)^2)=a`,

`CD=√((a-a)^2+(a-0)^2)=a`and

`DA=√((0-0)^2+(a-0)^2)=a`

Since, all the sides of the given polygon are equal, therefore it is a square.
