Answer 3

A right equilateral triangle cannot exist because an equilateral triangle has all three sides equal in length, which means all three angles are also equal. In an equilateral triangle, each angle measures 60 degrees. However, in a right triangle, one angle measures 90 degrees. Therefore, a triangle cannot have both 90 degree angle and 60 degree angles, which are required for being both right and equilateral.
