What is the relationship between the angle of an inscribed arc and the measure of its corresponding central angle?

The measure of an inscribed angle is always half the measure of its corresponding central angle. In other words, the central angle is twice the measure of the inscribed angle that subtends the same arc. This relationship holds true for any inscribed angle in a circle.

How can we determine the measure of a central angle given the measure of its intercepted arc?

To determine the measure of a central angle given the measure of its intercepted arc, simply use the fact that the measure of a central angle is equal to the measure of its intercepted arc. Therefore, if you know the measure of the intercepted arc, that is also the measure of the central angle.

What is the formula for calculating the circumference of a circle?

The formula for calculating the circumference of a circle is C = 2?r, where C represents the circumference, ? is a mathematical constant approximately equal to 3.14159, and r is the radius of the circle.

How do we find the length of an arc given its central angle and the radius of the circle?

To find the length of an arc given its central angle and the radius of the circle, you can use the formula: Arc length = (central angle / 360) x (2 x ? x radius). Simply divide the central angle by 360 to get the fraction of the circle the arc covers, then multiply that by the circumference of the circle (2 x ? x radius) to determine the arc length.

What is the definition of a tangent line in relation to a circle?

A tangent line in relation to a circle is a straight line that touches the circle at exactly one point, without crossing through the circle's interior. This point of contact is known as the point of tangency, and the tangent line is perpendicular to the circle's radius at that point.

How do we find the equation of a circle given its center and radius?

To find the equation of a circle given its center coordinates (h, k) and radius r, the standard form is (x - h)^2 + (y - k)^2 = r^2. This means the equation represents all points (x, y) that are a distance r away from the center (h, k) of the circle. Simply plug in the values of the center (h, k) and radius r to form the equation of the circle.

What is the formula for finding the area of a sector of a circle?

The formula for finding the area of a sector of a circle is A = (?/360) x ? x r^2, where A represents the area of the sector, ? is the central angle of the sector in degrees, ? is a mathematical constant approximately equal to 3.14159, and r is the radius of the circle.

How can we determine the measure of a minor arc given the measure of its corresponding major arc?

To determine the measure of a minor arc given the measure of its corresponding major arc, you can subtract the measure of the major arc from 360°. This will give you the measure of the central angle, which is equivalent to the measure of the minor arc. This is based on the property that the central angle formed by an arc is always equal in measure to the arc itself.

What is the relationship between the radius and diameter of a circle?

The diameter of a circle is always twice the length of its radius. In other words, the diameter is the distance across the circle through its center, while the radius is the distance from the center to any point on the circle's edge. So, the relationship between the radius and diameter of a circle is that the diameter is always two times the length of the radius.

How do we find the measure of an inscribed angle given the measure of its intercepted arc?

To find the measure of an inscribed angle given the measure of its intercepted arc, you need to use the relationship that the measure of an inscribed angle is half the measure of its intercepted arc. So, if you know the measure of the intercepted arc, you can simply divide it by 2 to find the measure of the inscribed angle.
