x,y describes the distance of the rectangle from the x and y axes
top, left, bottom, right # describes the size of the rectangle in the coordinate system
topleft, bottomleft, topright, bottomright #returns a tuple describing the size of the rectangle
midtop, midleft, midbottom, midright #returns a tuple describing the size of the rectangle
center, centerx, centery #(centerx, centery) represents the value of the central coordinate (x,y) of the rectangle
size, width, height
w,h # for describing the width, height of the rectangle
