Like all triangles an Isosceles triangle has three sides and three angles. However, in an Isosceles triangle , two of the three sides are the SAME length. Also in an Isosceles triangle, two of the angles of the three have the same degree value. Here are the names of different type of triangle. EQUILATERAL ; All sides the same length , all angles at 60 degrees. ISOSCELES ; As above RIGHT-ANGLED(90 DEGREE) One angle MUST be 90 degrees. SCALENE ; All three sides of different lengths and all three angles of different degree values. In all CASES the sum of the interior angles is ALWAYS 180 degrees.
A heptagon has 5 triangles.
