ACCESS - Chords and Arcs
BC and DE are chords on circle A. Drag B, C, D, and E to adjust the length of the chords. Arc BC (blue) and Arc DE (green) are the associated arcs.
1. Make chords BC and DE equal in length. How are the arc lengths related? Try this for a few lengths of BC and DE to verify.
2. Make BC and DE unequal. Does the longer chord or the shorter chord have the longer arc?
