In collections Rectangle: Fixed Perimeter
This example demonstrates how dragging the base and height of a rectangle changes its perimeter. It involves core math concepts like perimeter calculation and variable relationships. Constructed using commands such as Ray, Point, Polygon, Perimeter, PointIn. Suitable for middle school mathematics teaching to visually understand the perimeter formula and variable dependencies.

GeoGebra Commands & Parameters

  1. Ray(A, (1, 0)) → a
  2. Point(a) → B
  3. Ray(A, (0, 1)) → b
  4. Point(b) → C
  5. Polygon(A, C, D, B) → poly1, a_1, c, d, b_1
  6. Perimeter(poly1) → perimeterpoly1
  7. PointIn(poly1) → Pointpoly1

AI Drawing Prompt Reference

Draw a rectangle with two sliders controlling its base and height to demonstrate how changes in the base and height affect the perimeter. Start by creating two rays extending from one vertex of the rectangle in horizontal and vertical directions, then place two points on these rays. Connect these points to the other two vertices to form the rectangle. Calculate and display the perimeter of the rectangle, and add a point inside the rectangle to indicate its area.
