Calculating the Perimeter of Polygons

The video tutorial explains the concept of perimeter in geometry, starting with its basic definition as the distance around a shape. It covers how to calculate the perimeter of various polygons, including rectangles, squares, triangles, and irregular polygons. The tutorial also touches on the challenges of calculating perimeters when curvature is involved, hinting at the need for calculus in such cases. The video concludes with a brief mention of circles, setting the stage for further exploration of curved shapes.
