Final answer:
The student's question involves dividing line segments in specific ratios, a geometric concept related to the section formula and similar figures.
Step-by-step explanation:
The question pertains to the division of line segments in a given ratio, which is a common problem in the field of geometry, a branch of mathematics. Although the provided reference information seems to be unrelated to the question, the underlying concept of dividing a line segment in a specific ratio is central to solving geometric problems involving similar triangles, trapezoids, and other figures where proportional reasoning is key. In the scenario described, point E divides the line segment PQ internally in the ratio of 1:2, meaning that PE:PQ = 1:2. Similarly, the point F divides the line segment QR such that QF:FR = 2:1. To explicitly answer a question like this, one would typically apply the concept of the section formula or similarity of triangles.
