Angle Bisector, Perpendicular Bisector and Median

①This example demonstrates the construction of angle bisectors, perpendicular bisectors, and medians within a triangle, and uses translation to create multiple copies, visually highlighting the relationships among these three special line segments. ②Core mathematical concepts include the angle bisector (dividing an angle into two equal parts), the perpendicular bisector (perpendicular to a segment and bisecting it), and the median (connecting a vertex to the midpoint of the opposite side), along with geometric construction and transformation. ③Construction details: The Polygon command is used to create the triangle, and the Translate command is applied to translate the triangle and its internal segments, generating multiple copies (e.g., A', B', C'), with text labels (text1, text2, etc.) annotating elements; objects include vertices A, B, C, sides a, b, c, and their translated counterparts. ④This is suitable for middle school geometry lessons or classroom activities, helping students understand the definitions and properties of special segments in triangles, and observe changes through dynamic translation to enhance spatial reasoning.
