In collections GCSE Higher Ch8 Transformations & Constructions
This example demonstrates the use of GeoGebra to perform enlargement transformations, particularly with positive fractional scale factors. Key mathematical concepts include similar transformations in geometry. Using the Polygon and Dilate commands, the original polygon and its enlarged version are constructed. Suitable for students at the junior high school level and above.

GeoGebra Commands & Parameters

  1. Polygon(A, B, C) → poly1, c, a, b
  2. Dilate(A, SF, Centre) → A'
  3. Dilate(B, SF, Centre) → B'
  4. Dilate(C, SF, Centre) → C'
  5. Polygon(A', B', C') → poly1', c', a', b'

AI Drawing Prompt Reference

Draw a triangle ABC, then enlarge it using a center point and a positive fractional scale factor to create a new triangle A'B'C'. Ensure that the new triangle is similar to the original triangle.
