WebA chord of a circle is a straight line segment whose endpoints both lie on the circle. Alternate segment theorem states that the angle between a chord and tangent through … WebOct 12, 2014 · First, since PQ is parallel to diameter OR, we know that arc PO = arc QR. So, we can apply a circle property that says inscribed angles holding/containing arcs (or chords) of equal length must have the same angle measurement. This means angle QOR must also be 35° Next, we'll apply the following property: WebIf O is centre of a circle and Chord PQ makes an angle 50° with the tangent PR at the point of contact P, find the angle made by the chord at the centre.
