WebInscribed angles subtended by the same arc are equal. If a pair of arcs in the same circle are congruent, their inscribed angles are equal. If a pair of circles are congruent, then inscribed angles subtended by congruent arcs, or arcs of equal measure, will be equal. Web18 mei 2024 · ( "Subtended" means produced by joining two lines from the end points of the arc to the center). An arc of length R where R is the radius of a circle, corresponds to an angle of 1 radian. So if the circumference of a circle is 2π R i.e 2π times R, the angle for a full circle will be 2π times 1 radian or 2π radians.
