Which diagram shows a set and subset that is correct? a.) triangle square b.) quadrilateral trapezoid c.) rhombus rectangle d.) parallelogram triangle

Option B is correct, i.e. Quadrilateral Trapezoid.

Step-by-step explanation:

A "set" is group of all elements which have some special relationship among them like set of Natural numbers (N), set of Real Numbers (R), set of Integers (Z) etc.

A "subset" is group of some elements which are part of some another larger set like Natural numbers (N) is subset of Real numbers (R), i.e. N ⊆ R.

In other words, "SET" behaves like a Big Family, and "SUBSET" behaves like a group of family members which are part of its Big Family.

Checking the given options:-

1. Triangle and Square are different.

2. Rhombus and Rectangle are different.

3. Parallelogram and Triangle are different.

But option B, i.e. Trapezoid is a family member of Quadrilateral Family.

Hence, option B is correct, i.e. Quadrilateral Trapezoid.

a² + b²= c²

24² + 7² = c²

c= 25
