Answer:
[tex]SM=SA+AM[/tex]
[tex]SA=AM[/tex]
Step-by-step explanation:
see the attached figure to better understand the problem
we know that
The points S,A and M are collinear because they lie on a straight line. Using addition of segments we get
[tex]SM=SA+AM[/tex]
The midpoint of a line segment divides the line segment into two congruent parts
If A is the midpoint of SM
then
[tex]SA=AM[/tex]
therefore
The equations that satisfy the fact are
[tex]SM=SA+AM[/tex]
[tex]SA=AM[/tex]
