What is the definition of a circle?

A circle is a round shape defined as a set of all points in a plane that are at a fixed distance, called the radius, from a given point, called the center.

What is the center of a circle?

The center of a circle is the point that is equidistant from all points on the circumference of the circle.

What is the radius of a circle?

The radius of a circle is the distance from the center of the circle to any point on its circumference, half the diameter of the circle.

What is the diameter of a circle?

The diameter of a circle is a straight line passing from one side of the circle to the other side through the center, and it is equal to twice the length of the radius of the circle.

What is a chord in a circle?

A chord in a circle is a line segment that connects two points on the circle's circumference. It does not necessarily pass through the center of the circle, and the length of the chord can vary depending on the two points chosen.

What is a secant in a circle?

A secant in a circle is a line that intersects the circle at two distinct points. This line extends beyond the circle on both sides and can be used to identify various properties and relationships within the circle, such as angles formed by the secant and the circle's center, or lengths of segments created by the secant.

What is a tangent in a circle?

In a circle, a tangent is a line that touches the circle at exactly one point, known as the point of tangency. This line is perpendicular to the radius of the circle at the point of tangency, creating a right angle with the circle at that point. Tangents play a key role in geometry and trigonometry, particularly in relation to the properties of circles and angles formed within them.

What is an arc in a circle?

An arc in a circle is a portion of the circle's circumference that is defined by two endpoints. It is a curved line segment that connects two points on the circle, and the length of the arc is proportional to the measure of the central angle formed by the two endpoints at the center of the circle.

What is the circumference of a circle?

The circumference of a circle is the distance around the outside of the circle. It is calculated using the formula C = 2?r, where C is the circumference and r is the radius of the circle.

What is the equation for the area of a circle?

The equation for the area of a circle is A = ?r^2, where A represents the area and r represents the radius of the circle.
