Match the vocabulary word with the correct definition. 1. an angle in the plane of a circle with the vertex at the center of the circle central angle 2. the union of the endpoints of a diameter and all points of the circle lying on one side of the diameter. minor arc 3. the union of two points of a circle, not the end points of a diameter; and all points of the circle that are in the exterior of the central angle whose sides contain the two points. major arc 4. the union of two points of a circle, not endpoints of a diameter, and all points of the circle that are in the interior of the central angle whose sides contain the two points semicircle

1. central angle

2. semicircle

3. major arc

4. minor arc

Step-by-step explanation:

1. central angle is an angle whose vertex rest on the center of a circle, with its sides containing two radii of the same circle.

2. semicircle is simply a half circle which is formed by cutting a full circle along a diameter (that is union of the endpoints of a diameter).

3. major arc is an arc that is larger than a semicircle and is bounded by a central angle whose angle is lesser than 180°.

4. minor arc is an arc that is smaller than a semicircle and is bounded by a central angle whose angle is greater than 180°.
