Sagot :
Answer:
Step-by-step explanation:
Sides: a = 130 b = 183.848 c = 130
Area: T = 8450
Perimeter: p = 443.848
Semiperimeter: s = 221.924
Angle ∠ A = α = 45° = 0.785 rad
Angle ∠ B = β = 90° = 1.571 rad
Angle ∠ C = γ = 45° = 0.785 rad
Height: ha = 130
Height: hb = 91.924
Height: hc = 130
Median: ma = 145.344
Median: mb = 91.924
Median: mc = 145.344
Inradius: r = 38.076
Circumradius: R = 91.924
Vertex coordinates: A[130; 0] B[0; 0] C[-0; 130]
Centroid: CG[43.333; 43.333]
Coordinates of the circumscribed circle: U[65; 65]
Coordinates of the inscribed circle: I[38.076; 38.076]
Exterior (or external, outer) angles of the triangle:
∠ A' = α' = 135° = 0.785 rad
∠ B' = β' = 90° = 1.571 rad
∠ C' = γ' = 135° = 0.785 rad
