Inscribed Angle Calculator
inscribed angle. Example: Angle in degrees: 60 degrees gives 30 degrees. Inscribed angle subtends same minor arc as supplied central angle. Flat Euclidean geometry in the stated units. No waste, thickness, structural advice or curved-earth inference. Only the stated forward job is supported; display rounding does not change the calculation.
Inscribed angle subtends same minor arc as supplied central angle. Flat Euclidean geometry in the stated units. No waste, thickness, structural advice or curved-earth inference. Only the stated forward job is supported; display rounding does not change the calculation. Derivation: Angles subtending the same minor arc obey the inscribed-angle theorem.
Accepted inputs: Angle in degrees: 0.001 to 179.999 degrees.
How the calculation works
inscribed angle = central angle /2
Worked example
With angle in degrees 60 degrees, inscribed angle is 30 degrees.
Assumptions and limits
