Locus of Midpoint of Two Points Moving at Equal Linear Speed on Two Circles

①Demonstrates the green flower-shaped locus formed by the midpoint of two points moving at equal linear speed on two circles; ②Core math concepts: parametric equations of circles, locus generation, relationship between linear and angular velocity, geometric transformations; ③Construction highlights: utilizes GeoGebra commands Circle, Point, Rotate, Midpoint, and Locus to dynamically trace the midpoint; ④Suitable for high school or early college geometry classes to visually demonstrate locus generation and parametric equations.
