scalene triangle | acute | obtuse | right scalene triangle

what is a scalene triangle(विषमभुज त्रिभुज):
Simple definition of scalene triangle is: A Triangle in which No equal angles and no equal sides

As you can see in above triangle all sides with different lengths(AB,BC,CA not equal in lenghts) and Angles also not equal(68,71,41), so a triangle with no equal sides and Angles called scalene triangle(see above image/picture of scalene triangle).sum of the angles of a triangle is always 180 degrees.

Area of a scalene triangle:
s = (a + b + c) / 2
area of scalene triangle = sqrt(s * (s - a) * (s - b) * (s - c))

Types Of scalene Triangles:
acute scalene triangle:
An ACUTE scalene(all angles are acute) triangle contains three acute angles (each angle of an acute triangle is less than 90 degrees).sum of the angles of a triangle is always 180 degrees.An acute triangle may be isosceles,scalene or equilateral.

obtuse scalene triangle:
Obtuse scalene triangles have one angle that is greater than 90° degrees.(Obtuse triangles have one obtuse angle).sum of the angles of a triangle is always 180 degrees.An obtuse triangle may be scalene or isosceles.

right scalene triangle:
The right scalene triangle has one 90 degree angle and two acute (< 90 degree) angles.sum of the angles of a triangle is always 180 degrees.A right triangle may be scalene or isosceles.
