Chord example geometry
WebAnswer: : A chord is a line segment that joins any two points on a circle Diagram 1 In other words, a chord is basically any line segment starting one one side of a circle, like point A in diagram 2 below, and ending on another side of the circle, like point B. Points A and B … WebExample: Calculate the arc length of a curve, whose endpoints touch a chord of the circle measuring 3 units. The radius of the circle is 2 units. We have, Chord length = 5 units Central angle = 2 units Step 1: Chord length = 3 ⇒ 2 (2) sin (θ/2) = 3 Step 2: Solving this, we get: sin (θ/2) = 0.75 ⇒ θ/2 = sin -1 (0.75) = 0.848 ⇒ θ = 1.696.

WebThe diameter of a circle is the longest chord. Secant: A secant is an extended chord of a circle. Line 2 ( l2) is the secant of the circle above. Arc: An arc is a curve along the outer line of the circle. Tangent: The tangent of a circle is a straight line that externally touches a circle, the circle’s outer line. WebApr 3, 2024 · For example, if the lengths of two sides of a triangle and the measure of the enclosed angle are known, the third side and the two remaining angles can be calculated. Such calculations distinguish trigonometry from geometry, which mainly investigates qualitative relations.

Figure 6.12.6 Solution Among properties of chords of a circle are the following: 1. Chords are equidistant from the center if and only if their lengths are equal. 2. Equal chords are subtended by equal angles from the center of the circle. 3. A chord that passes through the center of a circle is called a diameter and is the longest chord of that specific circle.
