30̊ 60̊ 90̊ triangle calculation formula:

• 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;
