Study Notes
Chords, Radii, and Diameters
- Chords are segments whose endpoints lie on the circumference of a circle.
- Radii are segments from the center of the circle to any point on the circle; all radii of a circle are equal.
- Diameters are special types of chords that pass through the center of the circle, effectively being twice the length of a radius.
Congruence Statements in Circle O
- In Circle O, if the diameter CD intersects line AB at point P, forming a right angle, the following congruence statements hold:
- AP is congruent to BP (AP = BP signifies symmetry about the diameter).
- OC is congruent to OD (OC = OD demonstrates that both segments extend from the center of the circle to the endpoints of the diameter, thus equal in length).
