Question

What universal set(s) would you propose for the given: The set of isosceles triangles.

Answer 1

Universal set : if we assume there are some sets A, B, C and U in such a way that A, B, C are subset of set U then, U is universal set of given sets. mathematically,
if $A\subset U,B\subset U\: \textbf{and}\:C\subset U$
then, U is universal set of given sets.

now come to the question,
We know that isosceles triangle is a type of triangle with any two of the angles equal in measure.
Thus, a set of triangles will contain all the isosceles triangles.

∴ universal set, U = {x: x is a triangle in plane}

Answer 2

Answer:

Set of all triangles in a plane .

Step-by-step explanation:

***********************************

Universal set is a set which

contains all the objects , including

itself .

***********************************

Given set is " The set of

Isosceles triangles "

Required Universal Set

" The set of all triangles in a

plane ".
