TriangleAngleGeometric Construction
This example demonstrates that Pythagoras' theorem applies to every right-angled triangle. Key mathematical concepts include the relationship between the sides of a right-angled triangle. Using GeoGebra commands such as Point, Segment, OrthogonalLine, etc., a right-angled triangle is constructed and the side length relationship is shown. Suitable for middle school and above students to learn geometry.

GeoGebra Commands & Parameters

  1. Point(Circle[A, a]) → B
  2. Segment(A, B) → b_1
  3. OrthogonalLine(A, b_1) → c
  4. Circle(A, b) → d
  5. Intersect(d, c) → C, D
  6. Polygon(A, D, B) → poly1, b_2, a_1, d_1
  7. Angle(B, A, D) → α
  8. Distance(d_1, b_2) → f

AI Drawing Prompt Reference

Draw a right triangle with point A as the right angle, and points B and D as the endpoints of the legs. Draw a line segment from A to B, then draw a perpendicular line segment from A, intersecting a circle centered at A to get points C and D. Connect points A, D, and B to form the triangle, measure the angle BAD, and calculate the length of AD.
