Given: AB = CD Prove: AC = BD

AC = AB + BC = 14 + 6 = 20

    BD = CD + BC = 14 + 6 = 20

Step-by-step explanation:

AB = CD because it was given as true,

BC = BC because of the reflexive postulate,

AB+BC = CD + BC because of the addition postulate.

MANY get very technical and say AB+BC=AC and CD+BC=BD from the partition postulate, and then you can use the substitution postulate to get your final statement AC=BD.

25 questions , because they start with 100.  

350-100=250 .  

. 250/10=25

step-by-step explanation:

first take off 100, then what x 10 = 250? that is your answer. (25)
