Homework #58

Statement Reason

1) Triangle PQR in inscribed in circle

O, Chord PQ = Chord PR

2) Arc PQ= Arc PR

3)Arc QR = Arc QR

4) Arc PQ+ Arc QR = Arc PR+

ArcQR

Arc PQR = Arc PRQ

1) Given

2) In a circle if 2 chords are congruent

then the intercepted arcs are congruent

3) Reflexive Property

4) Addition postulate (steps 2,3)
