Question

If segment XY = XY which property is it?

transitive property of equality
reflexitive property of segement congruence
substitution property of equality
symmetric property of segment congruence

Answer 1

i'm sure you can find these definitions in your notes and text
but I thought that this might narrow the search down
transitive property
is
if a=b and b=c then a=c

reflexive property
is
a=a

symmetric property is
if a=b, then b=a
