Acute scalene triangle.
Sides: a = 7   b = 5.639   c = 5.482
Area: T = 15.12
Perimeter: p = 18.121
Semiperimeter: s = 9.061
Angle ∠ A = α = 78° = 1.361 rad
Angle ∠ B = β = 52° = 0.908 rad
Angle ∠ C = γ = 50° = 0.873 rad
Height: ha = 4.32
Height: hb = 5.362
Height: hc = 5.516
Median: ma = 4.322
Median: mb = 5.619
Median: mc = 5.735
Inradius: r = 1.669
Circumradius: R = 3.578
Vertex coordinates: A[5.482; 0] B[0; 0] C[4.31; 5.516]
Centroid: CG[3.264; 1.839]
Coordinates of the circumcenter: U[2.741; 2.3]
