The intersecting chords theorem or just the chord theorem is a statement in elementary geometry that describes a relation of the four line segments created by two intersecting chords within a circle. It states that the products of the lengths of the line segments on each chord are equal. It is Proposition 35 of Book 3 of Euclid's Elements. WebAlternate Segment Theorem. The segment of a circle is the region between a chord and the corresponding arc of the circle. When a chord is drawn, it creates a major segment and a minor segment in the circle. Let's observe the figure given below, in which DE is the tangent and BC is a chord. ∠ ∠ BCE is made by the tangent and chord BC.

Alternate Segment Theorem Brilliant Math & Science Wiki
WebThe theorem can also be thought of as a special case of the intersecting chords theorem for a circle, since the converse of Thales' theorem ensures that the hypotenuse of the right angled triangle is the diameter of its circumcircle.. The converse statement is true as well. Any triangle, in which the altitude equals the geometric mean of the two line segments … WebL is 1/2 the chord length. r is the same radius you already found. So we already know 2 sides for this triangle and just need to solve for L and double it to get the second chord length. r^2=a^2+L^2. L^2=r^2-a^2 = 35.23^2-17^2. L= sqrt (35.23^2-17^2) L=30.85. Just double that to get the length of the second cord. WebThis is stated as a theorem. Figure 1 Two chords intersecting inside a circle. Theorem 83: If two chords intersect inside a circle, then the product of the segments of one chord equals the product of the segments of the … playing a straight bat
