Some facts
 A triangle is a polygon with three edges and three vertices.
 The sum of angles in triangle is 180 degrees or π radians.
$\alpha + \beta + \gamma = \pi = 180 ^\circ$
 Due to length of the sides we distinguish below types of triangles:
 scalene triangle  all sides have different length,
 isosceles triangle  at least two sides have the same length,
 equilateral triangle  all sides have the same length.
 scalene triangle  all sides have different length,
 Due to angles measure we distinguish below types of triangles:
 acute triangle  all angles measure less than 90 degrees (π/2 radians),
 right triangle  one of angle measures exacly 90 degrees (π/2 radians),
 obtuse triangle  one of angle measures greater than 90 degrees (π/2 radians).
 acute triangle  all angles measure less than 90 degrees (π/2 radians),
