Given: circle P with diameter RS TW
prove: RTW is isosceles

Step-by-step explanation:

First, the RS is perpendicular to TW. That is paired with "Given".

Then arc mTR = arc mRW. This is paired with, "Diameter perpendicular to a chord bisects major arcs".

After that, chord TR = chord RW. You'll pair this up with "If arcs are =, chords are =".

Finally you'll pair Triangle TRW is isosceles with "Definition".

RS perpindicular TW       Given

m RT= m RW                     Diameter perpindicular to chord bisects major arcs

TR = TW                             If arcs are =, chords are =

TRW is issocolees            Definition
