The question is to prove that


AD=3AB

From the diagram in the question, we can deduce that


AD=AB+BC+CD\text{ (TOTAL DIsTANCE FOR THE LINE)}

Also given from the question, we have

B is the midpoint of AC, that is


AB=BC(\text{ B bisects AC into two equal parts)}

Also given from the question, we have

C is the midpoint of BD, that is


BC=CD\text{ ( C bisects BD into two equal parts)}

Therefore,

since BC=CD ,and BC=AB then,


CD=AB\text{ (THE LINE IS DIVIDED INTO EQUAL SEGMENTS)}

By substituting the values of BC and CD in the total distance for the line , we will have


\begin{gathered} AD=AB+BC+CD \\ AD=AB+AB+AB \\ AD=3AB\text{ (AD IS 3 times the length of AB because the line is divided into equal lengths)} \\ \text{PROVED} \end{gathered}
