A triangle in which one angle is equal to 90o is called a right triangle.
A triangle in which all sides are equal (or) all the angles are equal to 60o is called an equilateral triangle.
A triangle in which any two sides or any two angles are equal is called an isosceles triangle.
A triangle in which all the sides or angles are different is called a scalene triangle.
It can be scalene or isosceles but not equilateral.

It can be scalene or isosceles but not equilateral.
There are FOUR(4) different types of triangle. EQUILATERAL ; All sides the same length , and all angles at 60 degrees. ISOSCELES ; Two sides the same length, and two angles of the same value. RIGHT-ANGLED ; Three sides of DIFFERENT lengths or two sides the same length, MUST contain a right-angle (90 degree). SCALENE ; All three sides of different length, and all three angles of different values. For ALL triangles drawn in 2-dimension , the sum of the interior angles must be 180 degrees. NB for a triangle drawn across a 3-dimensional surface (sphere), the sum of the interior angles may be greater than 180 degrees.
Either an isosceles or a scalene triangle can have one right angle.
