(i) The set of right triangles
(ii) The set of isosceles triangles
What universal set (s) would you propose for each of the following?
(i) The set of right triangles
(ii) The set of isosceles triangles
(i) For the set of right triangles, the universal set can be the set of triangles or the set of polygons.
(ii) For the set of isosceles triangles, the universal set can be the set of triangles or the set of polygons or the set of two-dimensional figures.
We know that the collection of all right angled triangle or the collection of isosceles triangles, both are in the set of all triangles so for each collection, the universal set U = set of all triangles.
(i) For the set of right triangles, the universal set can be the set of triangles or the set of polygons.
(ii) For the set of isosceles triangles, the universal set can be the set of triangles or the set of polygons or the set of two-dimensional figures.
