In geometry, an inscribed angle is the angle formed in the interior of a circle when two chords intersect on the circle . It can also be defined as the angle subtended at a point on the circle by two given points on the circle. Equivalently, an inscribed angle is defined by two chords of the circle sharing an endpoint.
The key to remember is that when two secants or chords intersect inside the circle, you will always add ! Thankfully, this scenario mimics the Inscribed Angle Theorem, where the inscribed angle is equal to half the intercepted arc, as ck-12 accurately states.
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 other chord .
Answer Expert Verified (a) Two diameters of a circle will necessarily intersect. ans- yes, true as the diameters of the circle is longest chord and is always in the centre in horizontal or vertical of the circle.. so thus we can say that it is true.
If two secants or chords intersect in the interior of a circle, then the measure of each angle formed is half the sum of the measures of its intercepted arcs . The measure of an inscribed angle is equal to half the measure of its intercepted arc.
Answer: Both the statements are true We know that a diameter of a circle will always pass through the center. Hence, the two diameters of a circle will necessarily intersect at the center.
REASONING When two chords intersect at the center of a circle, are the measures of the intercepting arcs sometimes, always, or never equal to each other? SOLUTION: Since the chords intersect at the center, the measure of each intercepted arc is equal to the measure of its related central angle .
True, Diameter pass through center of circle. So, two diameter will always intersect at the center .
