WebIntersecting Chords Angle Theorem The measure of the angle formed by two chords that intersect inside a circle is the average of the measure of the intercepted arcs. An angle is considered to be outside a circle if the vertex of the angle is outside the circle and the sides are tangents or secants. WebPT is a tangent to the circle, PS = 9 cm and SR = 7 cm. Calculate the length PT. PR = IOcm, Find srll 4 cm and QT = 8 cm. AC = 30crn and AB = 14 cm. Calculate CE when …

WebA 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. Three theorems exist concerning the above segments. Theorem 1 PARGRAPH When two chords of the same circle intersect, each chord is divided into two segments by the other chord.
