Arc and Chord Relationship
Every circle arc has a close relationship with the chord that connects its two endpoints. A chord is a straight line connecting two endpoints of an arc, while an arc is a curved path along the circle's circumference. Imagine it like a bow and arrow, where the string is the straight line and the bow is the curved wood.
This relationship is very important in various engineering and architectural applications. The longer the arc, the longer the chord that connects it, but this relationship is not linear.
