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

"T is a subset of P"

Not true since triangle has three sides but parallelogram has four sides.

"E is a subset of I"

True since equilateral triangles are isosceles triangles with all angles equal.

"S is a subset of T"

True since scalene triangles are still triangle.

"I ⊂ E"

False since there are isosceles triangles those are not equilateral triangles. Namely triangle with angles 20°, 20°, 140°

"T ⊂ E"

False since not all triangles are equilateral. Scalene triangle is one of counterexamples.

"R ⊂ P"

True since rectangles are parallelograms with right angles.

Final  E is a subset of I, S is a subset of T, and R ⊂ P.

Hope this helps.
