Set of all points in the plane at a fixed distance(radius) from a fixed point(center)

Question 2

Radius

Question 3

Concentric

Answer 3

Coplanar circles with the same center

Question 4

Chord

Answer 4

Segment whose endpoints are on the circle

Question 5

Diameter

Answer 5

Chord that contains the center of the circle

Question 6

Central angle

Answer 6

Angle whose vertex is the center of the circle

In a circle the degree measure of a central angle is equal to the degree measure of its intercepted arc

Question 7

Inscribed angle

Answer 7

Angle whose vertex is on the circle and whose sides contain chords of the circle

The measure of an inscribed circle is half the measure of its intercepted arc
