1.) The polygon whose vertices in the coordinate plane are (-2,3) (2,3) (2,0) (-2,0) is a rectangle with length = 4 units and width = 3 units.
Therefore, only equiangular.
2.) The polygon whose vertices in the coordinate plane are (3,3) (5,0) (5,-3) (1,-3) (1,0) is a triangle on top of a rectangle which is neither equilateral nor equiangular nor regular.
i.e. none of the above.
3.) The polygon whose vertices in the coordinate plane are (5,0) (5,-3) (1,-3) (1,0) is a rectangle.
Therefore, it is only equiangular.
