Obtuse Triangle
Types of triangle ; EQUILATERAL all three sides the same length and all three angles are 60 degrees. ISOSCELES Two sides the same length and two angles have the same degrees value. RIGHT-ANGLED All three sides can be of different lengths. However, it MUST have one Right-Angle (90 degrees) SCALENE All three sides of different lengths and all three angles of different angular values. NB In ALL four cases the sum of the interior angles MUST ADD TO 180 DEGREES.
A right triangle has one angle that is a right angle (90 degrees). An obtuse triangle has one angle that is obtuse (between 90 and 180 degrees). An acute triangle is a triangle in which all three angles are acute (less than 90 degrees).
