With two values all remaining details of an arc can be calculated. Currently supports 21 combinations of: Angle, Radius, Arc Length, Chord Length, Tangent Length, Middle Ordinate, Segment Area and Sector Area. The only combinations that cannot be calculated have an infinite amount of solutions. Just fill in any two boxes and then click calculate or done. Instructions can be found on the main screen by clicking the "?". Formulae and information about arcs can be found by clicking the "i". Be aware that some solutions can have two possible answers, for example using the Radius and C
ArcCalc is a free educational mobile app By .It helps students in grades HS practice the following standards HSG.C.A.2.
1. HSG.C.A.2 : Identify and describe relationships among inscribed angles, radii, and chords. Include the relationship between central, inscribed, and circumscribed angles; inscribed angles on a diameter are right angles; the radius of a circle is perpendicular to the tangent where the radius intersects the circle.
