Question

rem 10.6 which is stated as follows:
the centre of a circle are equal
le make equal angles with the diameter
use of the above results:
e that the chords are equal.
Two careles of radu sem and 3 cm intersect at two points and the distance between
their centres is 4 cm. Find the length of the common chord.
If two equal chords of a circle intersect within the circle, prove that the segments of
one chod are equal to corresponding segments of the other chord.
I wo equal chords of a circle intersect within the circle prove that the line
Joining the point of intersection to the centre makes equal angles with the chords.
If a line intersects two concentric circles (circles
with the same centre) with centre O at A.B.C and
D. prove that AR CD (see Fig. 10.25).
Three girls Reshma, Salma and Mandip are
playing a game by standing on a circle of radius
5m drawn in a park Reshma throws a ball to
Salma, Salma to Mandip. Mandip to Reshma. If
the distance between Reshma and Salma and
between Salma and Mandip is om each, what is
the distance between Reshma and Mandip?
A circular park of radius 20m is situated in a colony. Three boys Ankur. Syed and

10.7 Angle Subtended by an Are of a Circle
You have seen that the end points of a chord other than diameter of a circle cuts it into
two arcs - one major and other minor. If you take two equal chords, what can you say
about the size of ares? Is one are made by first chord equal to the corresponding are
made by another chord? In fact, they are more than just equal in length. They are
congruent in the sense that if one arc is put on the other, without bending or twisting,
one superimposes the other completely.
You can verify this fact by cutting the arc,
corresponding to the chord CD from the circle along
CD and put it on the corresponding are made by equal
