This example demonstrates how to construct the perpendicular bisector of a segment using GeoGebra and explore its properties. The core math concepts involved include the midpoint of a segment, perpendicular lines, and angles. Construction highlights: Using GeoGebra commands/objects like Segment, Midpoint, OrthogonalLine, Point, and Angle; objects include A, B, f, M, g, C, h, i, text1, text2, a, α, β, b, c. Suitable for middle school and above mathematics education, for geometric construction and property exploration.

GeoGebra Commands & Parameters

  1. Segment(A, B) → f
  2. Midpoint(A, B) → M
  3. OrthogonalLine(M, f) → g
  4. Point(g) → C
  5. Segment(C, A) → h
  6. Segment(C, B) → i
  7. Angle(B, M, C) → α
  8. Angle(C, M, A) → β

AI Drawing Prompt Reference

Draw a line segment, find its midpoint, then construct a line perpendicular to the segment at the midpoint. Take a point on the line segment and connect it to the endpoints, forming two triangles. Measure and label the angles in these triangles to explore the properties of the perpendicular bisector.
