Compare and contrast the following parts of a circle: chord, central angle, arc, sector, and segment. Explain how the parts relate to each other and how they are different from each other.

By comparing these concepts we realize that they are related to circles. For instance, a segment comes up from cutting a circle by a line, and this line is a chord. On the other hand, whenever two lines, rays or line segments meet, they form an angle. The measure of an angle is found when y rotating one of the lines so it lies on the top of the other. So the central angle comes up from the lines between the radii of a circle. All the concepts are related to each other by the concept of circles, but they are different because they measure different things. For instance, the length of a chord can be measured in unit of length while the sector can be measured unit of area.

Answer:

Chord, central angle, arc, sector, and segment are related to each other as they all are parts of circle only .

They all are different from each other as chord and arc are measured in units whereas sector and segment are measured in unit squares .

Central angle is measured in degree or radians

Step-by-step explanation:

Chord is a line segment joining any two points of a circle .

Central angle is an angle formed by two radii at the centre of a circle .

Arc is the part of circle's circumference .

Sector is a part between two radii and the arc of circle .

Segment is a part between the chord and arc of circle .

They are related to each other as they all are parts of circle only .

They all are different from each other as chord and arc are measured in units whereas sector and segment are measured in unit squares .

Central angle is measured in degree or radians .
