Notes on Segment Addition Postulate, Angle Addition Postulate and Midpoints

Due to the pandemic, these are the notes for Geometry class today.
Topics covered:
Segment Addition Postulate: Basically, if you add two parts of a segment together, you get the whole thing.

(length of AB) + (length of BC) = (length of AC)

Angle Addition Postulate: same thing as above, only with angles.

Definition of Midpoint: If M is the midpoint of segment AB, then...
(Length of AM) = (Length of MB)
