Page 5 - Lesson note 4 Equal Chords-equidistant- circle Ch.- 10 Circle

Since RC = CM (from (2), we have
RM = 2(19.2) = 38.4
So, the distance between Ishita and Nisha is 38.4 m.

Example 3 : If two intersecting chords of a circle make equal angles with
the diameter passing through their point of intersection, prove that the
chords are equal.
