Question

{x : x is an equilateral triangle in a plane} _____ {x : x is a triangle in the same plane} Make correct statement by filling in the symbols $\subset or \not \subset$. in the blank space.

Answer 1

we know, A set is known as subset of another set if all elements of the set are elements of the set. for example :- set A = {a, e, i} and set B = {a, b, c , d , e , f , g , h , i} are given then, we can say set A is subset of set B, because all elements of set A are elements of set B. hence, we can write it $A\subset B$.

we know, equilateral triangle is a type of triangle . so, the set of equilateral triangles in a plane is subset of the set of any triangles in a plane.
so, {x : x is an equilateral triangle in a plane} $\subset$ {x : x is a triangle in the same plane}

Answer 2

Answer:

its is  a subset

Step-by-step explanation:

{x : x is an equilateral triangle in a plane} ⊂{x : x is a triangle in the same plane}
