Geometry - Proving a common centroid.












2












$begingroup$



Triangle PQR is drawn. Through it's vertices are lines drawn which are
parallel to the opposite sides of the triangle. The new triangle formed
is ABC. Prove that these two triangles have a common centroid.




I started by letting $M$ be the median of $[PQ]$, and then prove that bisector of $[BC]$ from $A$ occurs at $R$ while $M$ is collinear to $[AP]$. Firstly, I'm not sure whether or not this will suffice in proving they share a common centroid, and secondly I'm not sure where to start with the proof as setting up similar triangles from the parallel lines identity has lead to nothing.

$PQCR$ and $PQRB$ are parallelograms by construction, hence: $PQ=BR=RC$ and $R$ is the midpoint of $BC$.



$PRQA$ is by construction a parallelogram, hence its diagonals $PQ$ and $AR$ meet at their common midpoint $M$.



It follows that median $AR$ of triangle $ABC$ lies on the same line as median $RM$ of triangle $PQR$. The same reasoning holds for the other medians of those triangles.



Hence the medians of triangle $ABC$ meet at the same point as the medians of triangle $PQR$.

So $BR=PQ=CR implies R$ is the midpoint of $BC$. Similarly, $Q,P$ are the respective midpoints. And now by symmetry, you can take half turn of the triangle $PQR$, and enlarge each of its sides by a scale factor of $2$ with respect to the centroid of $Delta PQR$, and now this triangle will completely coincide with $ABC$, indeed implying it shares its centroid with the other triangle.

Solution with vectors. The centroid $G$ of $ABC$ is $G = {1over 3}(A+B+C)$



Since $R$ is a midpoint of $BC$ we have $$R = {1over 2}(B+C)$$ and similar for $P$ and $Q$. Now the centroid $G'$ of $PRQ$ is $$G' = {1over 3}(P+Q+R) = {1over 3}Big({1over 2}(B+C)+{1over 2}(A+C)+ {1over 2}(B+A)Big) $$$$= {1over 3}(A+B+C) = G$$
