Circle and chords rules
WebA number of interesting theorems arise from the relationships between chords, secant segments, and tangent segments that intersect. First of all, we must define a secant segment. A secant segment is a segment with one endpoint on a circle, one endpoint outside the circle, and one point between these points that intersects the circle. Web4. Theorem 4: The line that is drawn through the center of the circle to the midpoint of the chords is perpendicular to it.In other words, any line from the center that bisects a chord is perpendicular to the chord.. 5. …

WebIntersecting Chords Theorem. This is the idea (a,b,c and d are lengths): And here it is with some actual values (measured only to whole numbers): And we get. 71 × 104 = 7384; 50 × 148 = 7400; Very close! If we … WebSep 4, 2024 · Solution. By Theorem 7.3. 3, A P = B P. So A B P is isosceles with ∠ P A B = ∠ P B A = 75 ∘. Therefore x ∘ = 90 ∘ − 75 ∘ = 15 ∘. Answer: x = 15. If each side of a polygon is tangent to a circle, the circle is said to be inscribed in the polygon and the polygon is said to be circumscribed about the circle.

WebIf two secant segments are drawn from a point outisde a circle, the product of the lengths (C + D) of one secant segment and its exteranal segment (D) equals the product of the lengths (A + B) of the other secant segment and its external segment (B).
