In Geoemetry, a *median* of a triangle is a line segment joining a vertex to the midpoint of the opposing side.

In the figure above, the medians are in red. Notice that each median *bisects* one side of the triangle, so that the two lengths on either side of the median are equal.

**Example:**Find \(x\) if \(CY = \frac{1}{2}x - 1\) and \(CZ = \frac{{2x - 9}}{2}\)

\(\frac{1}{2}x - 1 = \frac{{2x - 9}}{2}\)

Multiplying both sides by 2 gives us

\(x - 2 = 2x - 9\)

Then solving for \(x\), we have

\(x = 7\)

So you see that the median can be useful for solving triangle problems.**Example:** Find \(x\) if \(FS = x\) and \(FY = x + 3\)**Solution:** Here the median \(FY\) passes through the centroid of the triangle. By the property of the centroid, this will cut the median \(FY\) into two segments \(FS\) and \(SY\) whose lengths are in the ratio 2:1. That is, if \(FS = x\), we have that \(SY = \frac{1}{2}x\). Then the sum of \(FS\) and \(SY\) is \(FY\). That is,

\(x + \frac{1}{2}x = x + 3\)

Then by multiplying both sides by 2, we have

\(2x + x = 2x + 6\)

and solving for \(x\) gives us \(x = 6\).
