The vertices of a triangle lie on a straight line.

The triangular region includes the vertices of a triangle.

Every triangle has three medians.

The altitude of a triangle drawn from a vertex to the opposite side, bisects the side.

From the given triangle, write the side opposite to vertex $P$, in $△PQR$.

From the given triangle, write the altitude from vertex $P$, in $△PQR$.

From the given triangle, The angle opposite to side $PQ$ in $△PQT$ is $\angle$?

From the given triangle, write the vertex opposite to side $PR$ in $△PSR$.

From the given triangle, write the median from vertex $P$, in $△PQR$.
