let `mu`= the set of all triangles, P = the set of all isosceles triangles, Q = the set of all equilateral triangles, R = the set of all right-angled triangles. What do the sets `PnnQ` and R-P represents respectively ?

Let U = the set of all triangles , P = the set of all isosceles triangles, Q - the set of all equilateral triangles , R = the set of all right angled triangles. What do the sets P uu Q represents ?

All equilateral triangles are isosceles also
