Answer:
Step-by-step explanation:
Given that in a circle Q, angle RQS= Angle SQT
Since central angles of two arcs are equal, by circle theorem we have the corresponding chords are equal
Hence RS =ST
REcall the theorem
Theorem 1: Equal chords of a circle subtend equal angles at the center
and also the converse
2. Theorem 2: This is the converse of the previous theorem. It implies that if two chords subtend equal angles at the center, they are equal.
