Study Notes
Inscribed Angles
- Inscribed angle measures are calculated as half of the measure of the outer arc.
Angles Outside a Circle
- The measure of an angle formed outside a circle equals half of the difference between the measures of the external arcs.
Angles Inside a Circle
- An angle found inside a circle is measured as half of the sum of the measures of the arcs outside the circle.
Chord Segments Theorem
- When two chords intersect within a circle, the products of the lengths of their chord segments are equal.
Secant Segments Theorem
- The product of the length of a short side of a secant line times the entire secant line equals the product of the length of the other short side with its entire secant line.
Tangent Secant Theorem
- Squaring the length of the unfinished short side of a tangent line equals the product of the length of the opposite short side and the length of its entire secant segment.
Equation of a Circle
- The standard equation for a circle is expressed as ((x - h)^2 + (y - k)^2 = r^2), where ((h, k)) is the center and (r) is the radius.
Circumference of a Circle
- The formula for calculating the circumference of a circle is (2 \pi \times \text{radius}).
Area of a Circle
- The area can be determined using the formula (\pi \times \text{radius}^2).
