A) Transitive Property B) Subtraction Property C) SSS Similarity Theorem D) Segment Addition Postulate

Answer 1

The correct option is Segment Addition Postulate

Explanation:

The segment addition postulate states that where there are two points on a line A and C and a third point B can only be located on the line segment AB if and only if the the distances between point A and point B as well as the distance between point B and point C satisfy the equation AB + BC = AC

Therefore, given that in the figure, the point B is in between point A and point C on segment AC then AB + BC

Similarly, AD = AE + ED.
