This example demonstrates the construction and analysis of a 30-60-90 right triangle using GeoGebra. It involves core mathematical concepts such as trigonometry, geometric constructions, coordinate systems, and properties of special triangles. Key GeoGebra commands and objects used in the construction include Intersect, Polygon, SurdText, Midpoint, and Angle. Suitable for high school mathematics education to understand the relationships between sides and angles in special triangles and construction techniques.

GeoGebra Commands & Parameters

  1. Intersect(xAxis, yAxis) → A
  2. Polygon(B, A, C) → poly1, c, b, a
  3. SurdText(long / sqrt(3)) → s
  4. Midpoint(b) → D
  5. SurdText((2 * long / sqrt(3))) → h
  6. Midpoint(a) → E
  7. Midpoint(B, A) → F
  8. Angle(poly1) → α, β, γ
