Question

the medians of $\triangle pqr$ are $\overline{pt}$, $\overline{qu}$, and $\overline{rs}$. they meet at a single point $v$. (in other words, $v$ is the centroid of $\triangle pqr$.) suppose $vu = 12$, $vs = 11$, and $pt = 27$. find the following lengths. note that the figure is not drawn to scale.

Explanation:

Step1: Recall centroid properties

The centroid of a triangle divides each median into a ratio of \(2:1\), with the longer segment being closer to the vertex. So, for median \(PT\), \(PV:VT = 2:1\), and \(PT=PV + VT\). Given \(PT = 27\), let \(PV = 2x\) and \(VT=x\). Then \(2x + x=27\), so \(3x = 27\), \(x = 9\), and \(PV=2\times9 = 18\).

Step2: For median \(QU\)

Since \(V\) is the centroid, \(QV:VU=2:1\). Given \(VU = 12\), then \(QV=2\times VU=2\times12 = 24\).

Step3: For median \(RS\)

Since \(V\) is the centroid, \(RV:VS = 2:1\). Given \(VS = 11\), then \(RV = 2\times11=22\). So \(RS=RV + VS=22 + 11=33\).

Answer:

\(PV = 18\), \(QV = 24\), \(RS = 33\)
