Consider the following amounts of plane figures: A = {All squares}, B = {all diamonds}, C = {all rectangles}, D = {all parallelograms}, E = {all trapezoidal with three equal sides}, F = {all trapezoidal with at least a straight corner angle}. Examine which of the following statements are true. Reply with the letter R (true) or F (false).
__________ (a) B U C= D
__________ (b) D ∩ F= C
__________ (c) D ∩ E= B
_________ (d) F "subset" D U E
__________ (e) E ∩ F= B ∩ C
Any advice?
