Construct the Perpendicular Bisector of a Segment

① This example demonstrates how to construct the perpendicular bisector of a given line segment using GeoGebra's construction tools, illustrating the geometric property that every point on the bisector is equidistant from the segment's endpoints. ② The core mathematical concept is the definition and properties of a perpendicular bisector, including its role in geometric constructions and its relation to equidistance. ③ Construction details: Based on the construction summary, the Segment command is used to create segment AB, with points A, B, C and a text object text1 involved; point C likely serves as the midpoint or an auxiliary point, and the perpendicular bisector is determined by constructing equal distances (possibly via circles or compass tools). ④ This is suitable for middle school geometry lessons or introductory geometric construction practice, helping students understand the construction process and become familiar with GeoGebra's basic commands.
