This example demonstrates the basic concepts of fractions, including addition and geometric mean. Using GeoGebra commands such as Intersect, Point, and Segment, the example constructs the numerator and denominator of a fraction. Suitable for high-grade elementary and junior high school students to learn basic fraction operations and concepts.

GeoGebra Commands & Parameters

  1. Intersect(xAxis, yAxis) → A
  2. Point(xAxis) → B
  3. Point(yAxis) → C
  4. Segment(A, B) → f
  5. Segment(B, D) → g
  6. Segment(D, C) → h
  7. Segment(C, A) → i
  8. Sequence(A + ((B - A) * t), t, 0, 1, 1 / penyebut) → L_1
  9. Sequence(C + ((D - C) * t), t, 0, 1, 1 / penyebut) → L_2
  10. Sequence(C + ((D - C) * t), t, 0, 1, 1 / penyebut) → L_3
  11. Sequence(Segment[Element[L_1, k], Element[L_2, k]], k, 1, penyebut) → L_4
  12. Sequence(Segment[Element[L_1, k], Element[L_2, k]], k, 1, penyebut) → L_5
  13. Point(Circle[A, a]) → E
  14. Polygon(A, E, F, C) → q1, a_1, e, f_1, c

AI Drawing Prompt Reference

Draw a coordinate plane with two perpendicular axes intersecting at the origin. Mark a point on the horizontal axis and another on the vertical axis, then connect the origin to these points with line segments, forming a right triangle. Divide the horizontal and vertical segments into equal parts, and connect corresponding division points with parallel lines to create a grid. Then draw a circle centered at the origin, pick a point on it, and form a quadrilateral using the origin, that point, and two other points. The figure illustrates fraction concepts through grid division and geometric shapes.
