Vertex coordinates: A[20; 0] B[0; 0] C[15; 8.66602540378]
Centroid: CG[11.66766666667; 2.88767513459]
Coordinates of the circumscribed circle: U[10; 0]
Coordinates of the inscribed circle: I[13.66602540378; 3.66602540378]

Exterior(or external, outer) angles of the triangle:
∠ A' = α' = 120° = 1.04771975512 rad
∠ B' = β' = 150° = 0.52435987756 rad
∠ C' = γ' = 90° = 1.57107963268 rad

# How did we calculate this triangle?

### 2. From cathetus b and hypotenuse c we calculate cathetus a - 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.
