Answer:
1. AO, CO, DO
2. CD
3. AB, CD
4. arc CAD, arc CBD
5. arc AC, arc AD
6. arc ADC, arc, ACD
7. angle AOC, angle AOD
Step-by-step explanation:
1. radius- half of the diameter
2. diameter- segment whose endpoints are on the circle and passes through the center of the circle.
3. chord- segment whose endpoints are any points on a circle
4. semicircle- an arc whose measure is half the circumference of a circle
5. minor arc- arc whose measure is less than the semicircle
6. major arc- arc whose measure is more than the semicircle
7. central angle- angle formed by 2 radii (plural form of radius) and whose vertex is at the center of the circle
