# In Exercises 21 to 26 , with P = { a l l   p o l y g o n s } as the universe, draw a Venn Diagram to represent the relationship between these sets. Describe a subset relationship, if one exists. Are the sets described disjoint or equivalent? Do the sets intersect? T = { traingles } ; I = { isosceles   triangles }

To determine

To draw:

The Venn diagram to represent the relationship between these sets and describe the subset relationship, if one exists and also determines that the set are disjoint or equivalent.

Explanation

Given:

The given sets are,

T={traingles}; I={isoscelestriangles}

Approach:

A set A is subset of another set if all elements of the set B if all elements of the set A are elements of the set B.

An isosceles triangle is always a triangle then I will be the subset of T.

Write the set relation between T and I.

IT

Draw the Venn diagram between the set of triangles and set of isosceles triangles.
