Teaching is very fun for me :))))

so first you plot the point in the paper and label each point by a letter

second find the length of each side

third by finding out the length you can figure out what is the best name of the quadrilateral that we asked about

you need to find the distance between each point and start figure out the actual quadrilateral, so lets see

if you assume that A(2,2),B(5,-2),D(1,-5),E(-2,-1)

the equation of the length between two point is known as : sqrt((x2-x1)^2+(y2-y1)^2)

by using this equation we will find the four sides length since we have four points

AB=sqrt((5-2)^2+(-2-2)^2)=5

AE=sqrt((-2-2)^2+(-1-2)^2)=5

ED=sqrt((1+2)^2+(-5+1)^2)=5

BD=sqrt((1-5)^2+(1-5)^2)=5

THE quadrilateral is a rhombus since all sides are equal length
