Select all the equations that satisfy this fact.
in the figure shown, a is the midpoint of sy.
o sa - am
osa + am - sm
osm + am - sa
o am + sm - sa

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

The midpoint of a line segment divides the line segment into two congruent parts

If A is the midpoint of SM

then

therefore

The equations that satisfy the fact are

hope this !
