              LINE SYMMETRY     Reflection symmetry, line symmetry, mirror symmetry, mirror-image symmetry, is symmetry with respect to reflection. That is, a figure which does not change upon undergoing a reflection has reflectional symmetry.                   ROTATIONAL SYMMETRY           Rotational symmetry , also known as radial  symmetry  in biology, is the property a shape has when it looks the same after some  rotation  by a partial turn. An object's degree of  rotational symmetry  is the number of distinct orientations in which it looks exactly the same for each  rotation

THE OF THE SYMMETRY OF REGULAR POLYGON

Image
        The polygon made up of the least number of line segments is the triangle.polygon is said to be regular if all its sides are of equal length and all its angles are of equal measure. Thus, an equilateral triangle is a regular polygon of three sides. An equilateral triangle is regular because each of its sides has same length and each of its angles measures 60°               A square is also regular because all its sides are of equal length and each of its angles  is a right angle (i.e., 90°). Its diagonals are seen to be  perpendicular bisectors of on another

Introduction

Image
      Symmetry is an important geometrical concept, commonly exhibited in nature and is used almost in every field of activity. Artists, professionals, designers of clothing or jewellery, car manufacturers, architects and many others make use of the idea of symmetry. The beehives,the flowers, the tree-leaves .       Something is symmetrical when it is  the same on both sides . A shape has symmetry if a central dividing line (a  mirror line ) can be drawn on it, to show that both sides of the shape are exactly the same .
