Question

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

Answer 1

Answer:

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°.
