Is this an angle or perpendicular bisector?

Question

a - Angle

b - Both

c - Perpendicular

d - Neither

Answer 1

know line RS is perpendicular to PQ,,,,two congruent triangles,,,,

all three angles same and triangles have have shared side

so angle PSR= angle QSR

PSR+QSR=180,,,2*PSR=180,,,angle PSR=90

since triangles are congruent lines PS=QS

so RS is perpendicular bisector for line PQ

line RS bisects angle PRQ is given in diagram.

Answer 2

RS bisects angle PRQ and is perpendicula bisctor or segment PQ
