CIRCULAR ARCH CALCULATOR

Circular Arch

Circle Sector, Segment, Chord and Arc Calculator

Lines AO and OB are called radii.
Lines AC, BC and AB are called chords.
The angle ACB is an inscribed angle.
The angle AOB is a central angle.
The curved line AB is called an arc.
Line OE is the apothem and is the height of triangle AOB.
Line ED is the segment height
