Question 100972: this a worksheet i do NOT understand. but if i know how to do at least one problem, i should be able to get them all. the directions are "Complete the argument, giving a reason for each step"
10. Given: (segment) JK is congruent to (segment) SH and (segment) SH is congruent to (segment) MN
Prove: (segment) JK is congruent to (segment) MN.
statement | reason
JK is congruent to SH ?
SH is congruent to MN ?
JK is congruent to MN segment addition postulate
i thought that the first two were given, but on the other ones it has given typed in, i found out the 3rd reason because our teacher gave us that one in class. I really don't know what to do, except we answer with a proof, properties, and/or postulates, and I appreciate your help.

If I understand your question correctly, this is just the associative property.
If a=b and b=c then a=c.
