This example demonstrates the geometric construction and properties of similar triangles and pyramids. It involves core mathematical concepts such as similarity criteria, polygon construction, transformation (dilation), orthocenter, and solid geometry. The construction uses GeoGebra commands like Polygon, Dilate, and Segment. Suitable for high school mathematics teaching to understand spatial geometry and transformation applications.

GeoGebra Commands & Parameters

Polygon(A, B, C) → poly1, c, a, b
Dilate(A, 3, D) → A'
Dilate(B, 3, D) → B'
Dilate(C, 3, D) → C'
Polygon(A', B', C') → poly1', c', a', b'
Dilate(A, 3, E) → A''
Dilate(B, 3, E) → B''
Dilate(C, 3, E) → C''
Polygon(A'', B'', C'') → poly1'_1, c'', a'', b''
Segment(A'', B'') → e
Segment(B'', C'') → f
Segment(C'', A'') → g
Segment(A', B') → h
Segment(B', C') → i
Segment(C', A') → j
