Circle chord math
WebThis is the reasoning: A circle has an angle of 2 π and an Area of: πr2. A Sector has an angle of θ instead of 2 π so its Area is : θ 2π × πr2. Which can be simplified to: θ 2 × r2. Area of Sector = θ 2 × r 2 (when θ is in radians) Area of … WebJun 15, 2024 · 1. Chord Theorem #1: In the same circle or congruent circles, minor arcs are congruent if and only if their corresponding chords are congruent. Figure 6.12.1. In both of these pictures, ¯ BE ≅ ¯ CD and ^ BE ≅ ^ CD. 2. Chord Theorem #2: The perpendicular bisector of a chord is also a diameter. Figure 6.12.2.
