Formulas of triangle with angle 30̊, 60̊ and 90̊:

• area = 0.5 * long side * short side;
• perimeter = long side + short side + hypotenuse;
• long side = hypotenuse * sin(60̊);
• long side = hypotenuse * 0.866025;
• short side = hypotenuse * 0.5;
• hypotenuse = long side * 1.1547;
• hypotenuse = short side * 2;
• short side = long side * cotangent(60̊) = 0.57735 * long side;
• long side = short side * tangent(60̊) = 1.732051 * short side;
