Introduction

Introduction A line of symmetry , , is a line separating a figure into two halves that are mirror images. Line symmetry exists for a figure if for every point P on one side of the line, there is a corresponding point Q where is the perpendicular bisector of .

Polygons

Polygons. A polygon is a closed figure in a plane formed by connecting line segments endpoint to endpoint, with each segment intersecting exactly two others Each segment is called a side of the polygon Each point where two segments meet is called a vertex of the polygon. Polygons.
