This applet demonstrates the properties of similar triangles. Key mathematical concepts include the definition and properties of similar triangles. Using GeoGebra commands such as Point, Segment, Polygon, etc., you can dynamically construct and observe similar triangles. Suitable for middle and high school students to learn about similar triangles.

GeoGebra Commands & Parameters

  1. Point(Circle[A, abs(AB)]) → B
  2. Segment(A, B) → a
  3. Circle(A, AC) → c
  4. Circle(B, BC) → d
  5. Intersect(c, d, 1) → C
  6. Segment(C, A) → b
  7. Segment(B, C) → e
  8. Polygon(A, B, C) → poly1, c_1, a_1, b_1
  9. Point(Circle[A', abs((k * AB))]) → B'
  10. Segment(A', B') → f
  11. Circle(A', (k * AC)) → g
  12. Circle(B', (k * BC)) → h
  13. Intersect(g, h) → C', G, ,
  14. Segment(C', A') → i
  15. Segment(C', B') → j
  16. Polygon(C', A', B') → poly2, e_1, f_1, d_1
  17. Textfield(AC) → inputBox1
  18. Textfield(AB) → inputBox2
  19. Textfield(BC) → inputBox3
  20. Textfield(k) → inputBox4
