This GeoGebra example demonstrates the animated translation of a graphic object named 'Kirk' (likely a custom image or geometric figure) driven by a vector, visually illustrating the geometric meaning of translation. The core mathematical concept is translation in the plane, a type of similarity transformation, involving vector representation and operations. Construction details: Point command creates key points A, B, C, D; Segment command constructs segments; Vector command defines translation vector u; Translate command translates object pic1 to produce images pic1' and pic1'', along with point C' and text1 for labeling. Suitable for middle school and above to understand coordinate/vector expressions of translation, also useful for high school analytic geometry or introductory linear transformations. Slider or animation controls enhance interactive learning.

GeoGebra Commands & Parameters

  1. Point(xAxis) → C
  2. Segment(B, C) → f
  3. Point(f) → D
  4. Vector(B, D) → u
  5. Translate(pic1, Vector[(0, 0)]) → pic1'
  6. Translate(pic1', u) → pic1''
  7. Translate(C, Vector[(5.160000000000005, -1.9399999999999973)]) → C'
