In this lesson our instructor talks about arcs and chords. First she discusses arcs and chords theorem 1. After, she lectures on inscribed polygons. Then she talks about arcs and chords theorem 2 and 3. Four complete extra example videos round up this lesson.
Arc of the chord: An arc that shares the same endpoints of the chord
In a circle or in congruent circles, two minor arcs are congruent if and only if their corresponding chords are congruent
Inscribed polygon: An inscribed polygon is a polygon inside the circle with all of its vertices on the circle
In a circle, if a diameter is perpendicular to a chord, then it bisects the chord and its arc
In a circle or in congruent circles, two chords are congruent if and only if they are equidistant from the center
