This example demonstrates the construction of a quadratic Bézier curve, which is a smooth curve defined by two control points and a base point. Using GeoGebra commands Segment and Locus, the curve generation process is dynamically shown. Suitable for high school mathematics education, particularly in coordinate geometry and parametric equations.

GeoGebra Commands & Parameters

  1. Segment(A, B) → f
  2. Segment(B, C) → g
  3. Segment(P, Q) → h
  4. Locus(R, t) → c

AI Drawing Prompt Reference

Draw a quadratic Bézier curve with points A and B as control points and point C as the base point. First, draw segment AB, then draw segment BC, and next draw segment PQ. Finally, generate the curve using the locus of point R as a function of parameter t.
The prompt above was compiled from the original drawing commands and is for reference only.
