CircleVectorGeometric Construction
In collections Jessica's Fraction Book
This example demonstrates the concept of fractions using circles and vectors, and how to construct them in GeoGebra. Commands used include Circle, Point, Append, CircleSector, Segment, Zip, and Textfield. Suitable for middle school and above students to learn the geometric representation of fractions.

GeoGebra Commands & Parameters

  1. Circle(C, r) → d
  2. Point(d) → D
  3. Append(Sequence[Rotate[D, s, C], s, (360 / m)°, 359.9*°, (360 / m)°], Rotate[D, 359.99*°, C]) → ListP2
  4. CircleSector(C, D, Element[ListP2, j]) → Shade2
  5. Segment(C, D) → b
  6. Zip(Segment[C, W], W, ListP2) → ListS2
  7. Textfield(m) → No
  8. Textfield(j) → inputBox1

AI Drawing Prompt Reference

Draw a circle C, then place m points D on the circle evenly, each point rotating 360/m degrees around the center C to form m sectors. Use these sectors and lines connecting the center C to each point D to illustrate the concept of fractions.
