MODELING WITH MATHEMATICS The diagram shows the position of the goalie and the puck during shows the position of the goalie and the puck during a hockey game. The goalie is at point G and the puck is at point $\mathrm{P}$ . a. What should be the relationship between $\mathrm{PG}$ and $\angle \mathrm{APB}$ to give the goalie equal distances to travel on each side of $\mathrm{PG}$ ? b. How does $\mathrm{m} \angle \mathrm{APB}$ change as the puck gets closer to the goal? Does this change make it easier or more difficult for the goalie to defend the goal? Explain your reasoning.

Key Concepts

Dynamic Variation in Angle Measures

This concept addresses how the measure of an angle can change in response to modifications in the positions of its defining points. Understanding this dynamic relationship is crucial in modeling situations where the configuration shifts over time, requiring an analysis of how such variations influence overall performance or strategy.

Angle Bisector Principle

The angle bisector principle asserts that a line dividing an angle into two equal parts creates symmetry within the geometric configuration. In many models, placing a reference (such as a point of movement or decision) along this bisector ensures equal measures or distances on either side, which is valuable for achieving balance or optimization in a system.

Geometric Relationships Between Angles and Distances

This concept explores how distances between points and the angles formed by connecting these points interact within a geometric configuration. It is essential for determining how changes in one measurement, such as distance, affect other aspects like the size of an angle, and is key to translating spatial problems into mathematical terms.

Mathematical Modeling

This concept involves representing real-world situations using mathematical tools, such as geometric figures and algebraic expressions. By abstracting the elements of a physical scenario into mathematical terms, one can analyze and predict behaviors, optimize decisions, and understand the relationships between different variables.
