Considering the sets, the statement which is true is 2. B ⊂ A
To answer the question, we need to know what polygons and sets are
What are polygons?
Polygons are plane shapes bounded by n sides. The number of sides determines the type of polygon.
Types of polygons
Some types of polygons include
- Triangles - These are 3 sided polygons
- Squares - These are 4 sided polygons
- Pentagons - These are 5 sided polygons
From this, we see that a triangle is a polygon with 3 sides.
What is a set?
A set is a collection of similar items.
Since
- set A = {x|x is a polygon} and
- set B {x|x is a triangle),
We see that B ⊂ A. Since triangles are 3 sided polygons.
So, the statement which is true is 2. B ⊂ A
