Isosceles triangle PQR is shown in the diagram. Which statement about the medians of the triangle PQR is true?
A). The medians of triangle PQR are concurrent at a point and the medians of the congruent sides of triangle PQR are congruent.
B). Each median of PQR bisects each of the other medians and creates bisected angles angles at the vertices of PQR.
C). The medians of PQR connect to create four congruent isosceles triangles in the interior of PQR.
D). The medians of PQR are perpendicular to the side opposite the vertex, creating two congruent triangles.
