1. TODAY IN GEOMETRY…  Warm Up: Major and Minor Arcs  Learning Target : 10.3 You will use relationships of arcs and chords in a circle.  Independent practice

2. WARM UP: Identify the arcs as a minor, major or semicircle. Then given the measurement of the arcs.

3. PROPERTIES OF CHORDS(3)

4. PROPERTIES OF CHORDS(1): In the same circle, or in congruent circles, two minor arcs are congruent if and only if their corresponding chords are congruent.

5. EXAMPLE:

6. PRACTICE:

7. PROPERTIES OF CHORDS(2): If a diameter of a circle is perpendicular to a chord, then the diameter bisects the chord and its arc.

8. EXAMPLE:

9. PRACTICE:

10. PROPERTIES OF CHORDS(3): If two chords are congruent, then they are equidistant from the center.

11. EXAMPLE: Radius

12. PRACTICE:
