WebThe Intersecting Chords Theorem asserts the following very useful fact: Given a point P in the interior of a circle, pass two lines through P that intersect the circle in points A and D and, respectively, B and C. Then AP·DP = BP·CP. The proof follows easily from the similarity of triangles ABP and CDP that is a consequence of the equality of ...

Problem. Prove the Tangent-Chord Theorem. Strategy. As we're dealing with a tangent line, we'll use the fact that the tangent is perpendicular to the radius at the …
WebJan 25, 2024 · 4. Chords of a circle that are equidistant from the centre of the circle are equal. Q.4. What is the chord and perpendicular theorem? Ans: A chord is a line segment joining any two points on the circumference of a circle. The chord and perpendicular theorem state that the perpendicular drawn from the centre of a circle bisects the chord. …
WebTheorem 1: The chord is bisected by a perpendicular drawn from the circle’s centre. To understand the theorem, consider the a circle, in which OP is the perpendicular bisector of chord AB and the chord is bisected into AP and PB. As a result, AP = PB.
