• consider the following sets: r = {x | x is the set of rectangles} p = {x | x is the set of parallelograms} t = {x | x is the set of triangles} i = {x | x is the set of isosceles triangles} e = {x | x is the set of equilateral triangles} s = {x | x is the set of scalene triangles} which statements are correct? check all that apply. t is a subset of p. e is a subset of i. s is a subset of t. i ⊂ e t ⊂ e r ⊂ p
