18 Ex 18.1 &#8211; Overview<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<h3><span class=\"ez-toc-section\" id=\"meaning-of-symmetry\"><\/span>Meaning Of Symmetry<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>If any given figure is being rotated within a specific central point, and after the rotation as well it seems to be the same way as it was before the rotation, then, that this figure has rotational symmetry. The multiple numbers of shapes in our geometry consist of rotational symmetrical shapes. Some of them are as follows:<\/p>\n<ul>\n<li>Circles<\/li>\n<li>Squares<\/li>\n<li>Rectangles<\/li>\n<li>Regular Polygons<\/li>\n<li>Center of Rotation<\/li>\n<li>Equilateral triangles<\/li>\n<\/ul>\n<p><strong>Centre of Rotation \u2013<\/strong> It can be defined as the fixed point, and around this point itself the rotation for the object having the rotational symmetry takes place. For example, a Windmill. The windmill\u2019s Centre is its centre of Rotation.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"scalene-triangle\"><\/span>Scalene Triangle<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>The Scalene Triangle has got no symmetry whenever we rotate it. The reason behind this is that it has an asymmetrical shape. There must be a minimum of two relevant identical orders to have symmetry.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"the-angle-of-rotational-symmetry\"><\/span>The Angle of Rotational Symmetry<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>The Angle of Rotational Symmetry can be defined as the angle of taking turns during the rotation taking place applicable to the object having the Rotational Symmetry. Eg: A square seems to be the same even after making the&nbsp; 90 degrees rotation. So, ideally, the figure of Square has 90 degrees as its angle of rotation.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"order-of-rotational-symmetry\"><\/span>Order of Rotational Symmetry<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>It can be defined as the total number of positions of rotation for a particular figure, as a result appearing the Same as it was before the rotation.<\/p>\n<p>The Order of Rotational Symmetry in the case of the regular hexagon is equivalent to the number 6 because it has 6 equal sides.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"rotational-symmetry-%e2%80%93-english-letters\"><\/span>Rotational Symmetry \u2013 English Letters<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>The multiple letters are said to have&nbsp;Rotational Symmetry at the time of their rotation in the clockwise or the anti-clockwise direction on its axis point.
