There are two main types of symmetry to consider:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Reflection symmetry (mirror symmetry):<\/strong> A letter has reflection symmetry if it can be divided into two equal halves that are mirror images. This can be vertical, horizontal, or both.<\/li>\n\n\n\n<li><strong>Rotational symmetry:<\/strong> A letter has rotational symmetry if it looks the same after being rotated 180 degrees (a half turn).<\/li>\n<\/ol>\n\n\n\n<p>To qualify for both reflection and rotational symmetry, a letter must remain unchanged when rotated 180 degrees and must also have a mirror image along at least one axis.<\/p>\n\n\n\n<p><strong>Letter H<\/strong> has both vertical and horizontal reflection symmetry. If split down the middle vertically or across the middle horizontally, the halves match. Additionally, when rotated 180 degrees, it looks the same.<\/p>\n\n\n\n<p><strong>Letter I<\/strong> has both vertical and horizontal reflection symmetry, depending on its font. It also has rotational symmetry because it appears the same when flipped upside down.<\/p>\n\n\n\n<p><strong>Letter O<\/strong> is a perfect example of both types of symmetry. It has infinite lines of reflection symmetry and looks identical when rotated by 180 degrees.<\/p>\n\n\n\n<p>These three letters meet the criteria because:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>They remain unchanged when turned halfway around (rotational symmetry).<\/li>\n\n\n\n<li>They can be split evenly into mirrored halves (reflection symmetry).<\/li>\n<\/ul>\n\n\n\n<p>Letters like X or N may appear symmetrical at first glance, but X has reflection symmetry but no proper rotational symmetry unless turned 90 degrees, which is not the standard for defining 180-degree rotational symmetry in this context. N fails rotational symmetry because it becomes a backward N when rotated.<\/p>\n\n\n\n<p>Therefore, <strong>H, I, and O<\/strong> are the correct capital letters that have <strong>both<\/strong> reflection symmetry and rotational symmetry.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Write three capital letters of the English alphabet which have both rotational symmetry and reflection symmetry.
