Question

match the part of the circle to its correct name.

a. ∠fjg
b. $widehat{ihf}$
c. $widehat{fgh}$
d. $widehat{if}$

1. central angle
2. semi - circle
3. major arc
4. minor arc

Explanation:

A central angle has its vertex at the center of the circle. $\angle FJG$ has vertex $J$ (center), so it's a central angle. A semi - circle is half of a circle. $\overparen{IHF}$ is half of the circle. A major arc is an arc that is greater than a semi - circle. $\overparen{FGH}$ is greater than half the circle. A minor arc is an arc that is less than a semi - circle. $\overparen{IF}$ is less than half the circle.

Answer:

a. 1. Central angle
b. 2. Semi - circle
c. 3. Major arc
d. 4. Minor arc
