Cheat Sheet
- Equation of a Circle -
The standard form of a circle centered at (h, k) is (x - h)² + (y - k)² = r², where r is the radius. Converting the general form x² + y² + Dx + Ey + F = 0 involves completing the square for x and y to identify the center and radius. Mastering this is essential for acing coordinate-based questions about circles in any circle quiz.
- Central and Inscribed Angles -
A central angle's measure equals its intercepted arc, while an inscribed angle measures half the intercepted arc (∠ABC = ½ arc AC). Thales' theorem is a handy mnemonic: any angle inscribed in a semicircle is 90°. Recognizing this relationship is crucial for many circle geometry questions and circles logic questions.
- Arc Length and Sector Area -
In radian measure, arc length ℓ = rθ and sector area A = ½r²θ, with θ in radians. If you have degrees, convert via θ(rad) = θ(°)·π/180 before applying formulas. These equations often appear in math circles trivia to test your fluency with circle segments.
- Chord Properties and Power of a Point -
When two chords intersect inside a circle, the products of their segments are equal: (AE·EB) = (CE·ED). For an external point, the power of a point theorem states (external segment)·(whole secant) = (tangent length)². These principles frequently surface in questions about circles involving segment lengths.
- Tangents, Secants, and Angle Theorems -
A tangent is perpendicular to the radius at the point of contact, and the angle between a tangent and chord equals the angle in the opposite arc. The secant - tangent power theorem (tan² = ext·whole) is a quick mnemonic for length problems. Mastering these theorems gives you confidence in every circle quiz challenge.
