In triangle abc ad/db = ce/eb. complete the proof showing the segment de is parallel to segment ac.
1.
a) (ad/db) + 1 = (ce/eb) + 1
b) (ad/db) + de = (ce/eb) + de
c) ad * eb = ce * db
2.
a) corresponding sides of congruent triangles are congruent.
b) addition property of equality
c) cross multiplication
edit: answer is 1.a and 2.b (verified correct) to

1.

2. Addition property of equality

Step-by-step explanation:

In triangle ABC,

The addition property of equality states that if the same amount is added to both sides of an equation, then the equality is still true.

Use addition property of equality, add 1 to both sides of previouse equality:

2 over 5

step-by-step explanation:

the 2: 3 ratio is the length of the ac segment to the cb segment total length. this implies that the ratio between segment ac length and segment ab length is 2: 5. point c is 2/5 from a to b, so the required fraction is 2/5.
