Calculate another triangle
How did we calculate this triangle?
1. Input data entered: hypotenuse c and angle α

2. From angle α we calculate angle β:

3. From hypotenuse c and angle α we calculate cathetus a:

4. From cathetus a and hypotenuse c we calculate cathetus b - Pythagorean theorem:

Now we know the lengths of all three sides of the triangle and the triangle is uniquely determined. Next we calculate another its characteristics - same procedure as calculation of the triangle from the known three sides SSS.

5. The triangle circumference is the sum of the lengths of its three sides

6. Semiperimeter of the triangle

7. The triangle area using Heron's formula

8. Calculate the heights of the triangle from its area.

9. Calculation of the inner angles of the triangle using a Law of Cosines

10. Inradius

11. Circumradius
