# Determine whether the set have a subset relationship. Are the two sets disjoint or equivalent? Do the set intersect? R={right triangles}, O={obtuse triangles}

Question
Determine whether the set have a subset relationship. Are the two sets disjoint or equivalent? Do the set intersect?
R={right triangles},
O={obtuse triangles}

A right triangle has a right angle and two acute angles and an obtuse triangle has an obtuse angle and two acute angles.
So, an obtuse triangle can never be a right triangle and vice - versa.
Thus, R and O are disjoint sets.
