ABIICD, AC=BD Theorem: In a circle, or congruent circles, congruent chords are equidistant from the center.
Circles Introduction. Notes, examples, formulas, and practice questions. Topics include parts of a circle, arc length, sector area, and more.
Math Formulas: Circle. Equation of a circle. In an x y coordinate system, the circle with center (a; b) and radius r is the set of all points (x; y) such that: 1. (x a)2 + (y b)2 = r2. Circle centered at the origin: 2. x2 + y2 = r2. Parametric equations. 3. where t is a parametric variable. = a + r cos t. = b + r sin t.
The formula for the area of a circle is: A = πr 2, where r is the radius of the circle. To find the area of a circle, follow these simple steps: find the radius of the circle (the distance from one side to the center of the circle).
