Question

An ___ is a portion of a circle. There are three types of these: minor, major, and semicircle. A semicircle measures 180 degrees, a minor one is shorter than a semicircle, and a major one is longer than a semicircle.

Answer 1

an arc is a portion of a circle.

Answer 2

The correct answer is an arc.

Step-by-step explanation:

An arc is one of the geometric figures that we can find inside a circle.

It is literally a portion of a circle, between two points that make it up, and all the points that are within that distance.

The way to measure them is through their angles where the vertex is in the center of the circle and extends until intercepting the points that are at the end of the arc.

We call a minor arc those whose angles are less than 180 °.

We call Semicircle those arcs whose angles are equal to 180 °.

And an arc that measures more than 180 ° is a major arc.
