Find the length of AB, given that be is a median of the triangle and AC = 30.

SOLUTION
Draw the diagram
a median of a triangle is a line segment joining a vertex to the midpoint of the opposite side, thus bisecting that side.
Hence
[tex]|DB|\text{ bisect |AC|}[/tex]SInce AC=30, Then
[tex]\begin{gathered} AB=15,\text{ CB= 15} \\ \text{Hence} \\ |AB|=15 \end{gathered}[/tex]Thus, from the median properties of a triangle, AB = 15
