This example demonstrates the geometric construction and properties of a fishing rod under the SSA case. It involves core mathematical concepts such as trigonometry, circles, reflection, and rotation. The construction utilizes GeoGebra commands like Intersect, Circle, Point, Ray, Rotate, Angle, Segment, and Corner. Suitable for high school mathematics education to understand geometric problems and construction methods in SSA cases.
