Definition of Midpoint 

Addition Property

 Subtraction Property

Answer 1

Diamond,

Without a diagram, it seems difficult to answer this question, but you don't have a lot of options, so here's what I think:

If the rods are placed end-to-end to make a longer rod in the diagram, then it is the "segment addition property", or in this case, the addition property.

All the addition properties--of segments, angles, etc.-- state that if you add two smaller things together, the equal the measure of the big thing.

I hope this helps, and have fun mathing!
