Answer:
Not a right triangle.
Step-by-step explanation:
Obtuse scalene triangle.
Sides: a = 33 b = 56 c = 66
Area: T = 923.419
Perimeter: p = 155
Semiperimeter: s = 77.5
Angle ∠ A = α = 29.979° = 29°58'45″ = 0.523 rad
Angle ∠ B = β = 57.99° = 57°59'22″ = 1.012 rad
Angle ∠ C = γ = 92.031° = 92°1'52″ = 1.606 rad
Height: ha = 55.965
Height: hb = 32.979
Height: hc = 27.982
Median: ma = 58.939
Median: mb = 44.028
Median: mc = 31.992
Inradius: r = 11.915
Circumradius: R = 33.021
Vertex coordinates: A[66; 0] B[0; 0] C[17.492; 27.982]
Centroid: CG[27.831; 9.327]
Coordinates of the circumscribed circle: U[33; -1.17]
Coordinates of the inscribed circle: I[21.5; 11.915]
Exterior (or external, outer) angles of the triangle:
∠ A' = α' = 150.021° = 150°1'15″ = 0.523 rad
∠ B' = β' = 122.01° = 122°38″ = 1.012 rad
∠ C' = γ' = 87.969° = 87°58'8″ = 1.606 rad
