Unit 11 Chords and Arcs Key Points
- Congruent Arcs and Chords:
- Statement: If two arcs of a circle (or congruent circles) are congruent, then their corresponding chords are equal in length.
- Explanation: If two arcs are the same size, the straight-line segments (chords) connecting their endpoints will also be the same length.
- Equal Chords and Corresponding Arcs:
- Statement: If two chords of a circle (or congruent circles) are equal, then their corresponding arcs (whether minor, major, or semi-circular) are congruent.
- Explanation: If the straight-line segments (chords) are equal in length, the curved parts (arcs) they cut out will also be equal.
- Equal Chords Subtending Equal Angles:
- Statement: Equal chords of a circle (or congruent circles) subtend equal angles at the center (or corresponding centers).
- Explanation: If two chords are equal, they will create the same angle at the center of the circle.
- Equal Angles Subtended by Equal Chords:
- Statement: If the angles subtended by two chords of a circle (or congruent circles) at the center (or corresponding centers) are equal, then the chords are equal.
- Explanation: If two angles at the center of the circle are equal, the chords that create those angles must also be equal in length.
