1. Segment Addition
Postulate
Victorino Gonzales Jr. III - Osias

2. I. Objective
OTo know how Segment
Addition Postulate can
be form.

3. II. Mission
O To educate students how
to write the Segment
Addition Postulate.

4. III. Motivation
O To Help students to learn
how Segment Addition
Postulate can be use.

5. Segment Addition Postulate
O Segment addition postulate states that if B
is between A and C, then AB + BC = AC.
If a point B lies on a line segment
, then

6. Example
O Find the length of DG and EG if DE = 20, EF
= 30 and FG = 40
Solution:
Finding DG
DG = 20 + 30 + 40 = 90
Finding EG
EF = 30 + 40 = 70

7. O The Segment Addition Postulate is
often used in geometric proofs to
designate an arbitrary point on a
segment. By choosing a point on the
segment that has a certain
relationship to other geometric
figures, one can usually facilitate the
completion of the proof in question.
