Question

Using the segment addition postulate, which is true?

AB + BC = AD
AB + BC = CD
BC + CD = AD
BC + CD = BD

Answer 1

BC+CD=BD

Explanation:

BD is divided up into 2 segements, BC, and CD so therefore, BC and CD equals BD

I hope this helps and please don't hesitate to ask if there is anything still unclear!

Answer 2

BD=BC+CD

Explanation:

We are given that

A =-6

B=-1

C=2

D=8

By using segment addition postulates

AD=AB+BC+CD

AD=AB+BD

BD=BC+CD

AC=AB+BC

Hence, option D is true.
