Used to find the Chord when any two of the three Radius, Angle° or Arc Length are known.
Enter any two of the three variables and the third is calculated. Changing one of the three will display this [icon--app-unknown-inverse] next to the other two, select the one you would like to recalculate.
Some times the Arc Length will equal the Chord. This is because they are close in value and the app is set to 16ths. You can change 16ths to 32nds or 64ths by selecting [icon--app-more] in upper right corner, then select Settings.

Can be used to layout circular stairs. Once the Chord and Arc Length are calculated you can open the calculator and select Arc Length from the template integration and divide it into individual stair treads to find the Chord of the treads.
