Perimeter of Irregular Shapes

This example demonstrates how to calculate the perimeter of irregular polygons, involving core math concepts like perimeter calculation, piecewise functions, dilation, trigonometric functions, boxplot, and hypothesis testing. It is constructed using GeoGebra commands like Textfield, Polygon, Perimeter, and objects such as A, B, C, D, E, F, G, H, J, K, L, poly1, etc. Suitable for high school and above mathematics teaching and geometric construction learning.
