How did we calculate this triangle?

1. Input data entered: cathetus a and inradius r 2. From cathetus a and inradius r we calculate cathetus b: 3. From cathetus a and cathetus b we calculate hypotenuse c - Pythagorean theorem: 4. From hypotenuse c and inradius r we calculate area S: 5. From area S and hypotenuse c we calculate height h: 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. 6. The triangle circumference is the sum of the lengths of its three sides 7. Semiperimeter of the triangle 8. The triangle area - from two legs 9. Calculate the heights of the triangle from its area. 10. Calculation of the inner angles of the triangle - basic use of sine function   13. Calculation of medians Trigonometry right triangle solver. You can calculate angles, sides (adjacent, opposite, hypotenuse) and area of any right-angled triangle and use it in real world to find height. A right-angled triangle is entirely determined by two independent properties. Step-by-step explanations are provided for each calculation.
