Takeaways

• 😀 The center of a circle is the equidistant point from any point on the circle's edge.
• 😀 The circumference is the measurement of the boundary of a circle (also known as its perimeter).
• 😀 An arc is a segment of the circle's circumference, representing a portion of its boundary.
• 😀 The radius is the distance from the center of the circle to any point on its circumference.
• 😀 A sector is a pie-shaped area of a circle formed by an arc and two radii.
• 😀 The diameter is the longest straight line that passes through the center of the circle, with endpoints on the circumference.
• 😀 A chord is any line segment that joins two points on the circumference of the circle.
• 😀 The diameter is the longest chord in a circle, as it passes through the center.
• 😀 A segment is the region enclosed by a chord and its corresponding arc, lying between the chord's endpoints.
• 😀 A secant is a straight line that intersects a circle at two points.
• 😀 A tangent is a line that touches the circle at exactly one point, without crossing it.

Q & A

What is the center of a circle?

The center of a circle is the point that is equidistant from every point on the circumference of the circle. It is the exact middle of the circle.

What is the circumference of a circle?

The circumference is the perimeter or boundary of the circle. It is the total distance around the circle.

What is an arc in the context of a circle?

An arc is a segment of the circumference of a circle. It is essentially a curved section of the circle's boundary.

How do you define the radius of a circle?

The radius of a circle is the distance from the center of the circle to any point on its edge. In the case of a sphere, it refers to the distance from the center to any point on its surface.

What is a sector of a circle?

A sector is a wedge-shaped area of a circle, formed by an arc and the two radii that connect the arc's endpoints to the center of the circle.

What is the diameter of a circle?

The diameter is a straight line passing through the center of the circle, with its endpoints touching the circle’s circumference. It is the longest possible chord in a circle.

What is a chord in a circle?

A chord is a straight line that connects any two points on the circumference of the circle. The diameter is a special type of chord, as it is the longest possible chord.

What does a segment of a circle refer to?

A segment of a circle is the area enclosed by a chord and the arc that connects the chord's endpoints. It is the region between the chord and the arc.

What is a secant in relation to a circle?

A secant is a straight line that intersects a circle at two distinct points, cutting through the circle.

What is a tangent to a circle?

A tangent is a straight line that touches the circle at exactly one point. It does not intersect the circle but merely touches the edge at a single point.
