If arcs AXB and CYD of a circle are congruent, find the ratio of AB and CD.
Given that arcs AXB and CYD are congruent arcs of a circle
To find: the ratio AB:CD
Join AB and CD
It is given that AXB and CYD are congruent arcs of a circle
Their respective chords will be equal.
So, AB = CD
Hence, the ratio of AB and CD is 1 : 1.
