A triangle has 3 sides, 3 vertices and 3 angles. There are different ways in which we can categorize the triangles. On the basis of sides, a triangle can be scalene, isosceles, or equilateral. However, in some cases, a triangle may possess unique properties. Such triangles are called special triangles. One such special triangle is the 30\u00b0\u201360\u00b0\u201390\u00b0 triangles.<\/p>\n\n\n\n<h2 class=\"wp-block-heading eplus-wrapper\" id=\"0-what-is-a-%E2%80%9C30-60-90%E2%80%9D-triangle\">What Is a \u201c30-60-90\u201d Triangle?<\/h2>\n\n\n\n<figure class=\"wp-block-image size-full eplus-wrapper\"><img loading=\"lazy\" decoding=\"async\" width=\"620\" height=\"326\" src=\"https:\/\/www.splashlearn.com\/math-vocabulary\/wp-content\/uploads\/2022\/06\/30-60-90-Triangle-1.png\" alt=\"30\u00b0\u201360\u00b0\u201390\u00b0 triangles\" class=\"wp-image-5759\" title=\"30\u00b0\u201360\u00b0\u201390\u00b0 triangles\" srcset=\"https:\/\/www.splashlearn.com\/math-vocabulary\/wp-content\/uploads\/2022\/06\/30-60-90-Triangle-1.png 620w, https:\/\/www.splashlearn.com\/math-vocabulary\/wp-content\/uploads\/2022\/06\/30-60-90-Triangle-1-300x158.png 300w\" sizes=\"auto, (max-width: 620px) 100vw, 620px\" \/><\/figure>\n\n\n\n<p class=\"eplus-wrapper wp-block-paragraph\">A special right triangle with angles 30\u00b0, 60\u00b0, and 90\u00b0 is called a 30-60-90 triangle. The angles of a 30-60-90 triangle are in the ratio 1 : 2 : 3. Since 30\u00b0 is the smallest angle in the triangle, the side opposite to the 30\u00b0 angle is always the smallest (shortest leg). The side opposite to the 60\u00b0 angle is the longer leg, and finally, the side opposite to the 90\u00b0 angle is the largest side of the right triangle, also known as the hypotenuse.<\/p>\n\n\n\n<p

Find the length of the hypotenuse in the following figure.<\/strong><\/p>\n\n\n\n<figure class=\"wp-block-image size-full eplus-wrapper\"><img loading=\"lazy\" decoding=\"async\" width=\"269\" height=\"191\" src=\"https:\/\/www.splashlearn.com\/math-vocabulary\/wp-content\/uploads\/2022\/06\/Solved-Example-2-2.png\" alt=\"Find the length of the hypotenuse\" class=\"wp-image-5768\" title=\"Find the length of the hypotenuse\"\/><\/figure>\n\n\n\n<p class=\"eplus-wrapper wp-block-paragraph\">Answer: Side opposite to 60\u02da, QR = a = 8\u221a3 cm&nbsp;<\/p>\n\n\n\n<p class=\"eplus-wrapper wp-block-paragraph\">The hypotenuse of the triangle, i.e., PR = $\\frac{2a}{\\sqrt{3}} = \\frac{2 \u00d7 8\u221a3}{\\sqrt{3}}$ = 16 units.&nbsp;<\/p>\n\n\n\n<p class=\"eplus-wrapper wp-block-paragraph\"><strong>3.&nbsp; <\/strong><strong>A triangle has sides 3\u221a2, 3\u221a6, and 3\u221a8.

Therefore, sides of the triangle are 3\u221a2, 3\u221a6, and 3\u221a8, are in the ratio 1: \u221a3: 2.<\/p>\n\n\n\n<p class=\"eplus-wrapper wp-block-paragraph\">The sides are following the 30-60-90 triangle rule. So, the angles of the given triangle&nbsp;are 30\u00b0, 60\u00b0, and 90\u00b0.<\/p>\n\n\n\n<h2 class=\"wp-block-heading eplus-wrapper\" id=\"5-practice-problems\">Practice Problems<\/h2>\n\n\n\n<p class=\"eplus-wrapper wp-block-paragraph\"><div class=\"spq_wrapper\"><h2 style=\"display:none;\">30 60 90 Triangle<\/h2><p style=\"display:none;\">Attend this Quiz & Test your knowledge.<\/p><div class=\"spq_question_wrapper\" data-answer=\"0\"><span class=\"spq_question_header\"><span class=\"sqp_question_number\">1<\/span><h3 class=\"sqp_question_text\">Which of the following forms a 30-60-90 triangle?<\/h3><\/span><div class=\"spq_answer_block\" data-value=\"0\">5, 5\u221a3, 10<\/div><div class=\"spq_answer_block\" data-value=\"1\">5, 5\u221a3, 20<\/div><div class=\"spq_answer_block\" data-value=\"2\">10, 5\u221a3, 10<\/div><div class=\"spq_answer_block\" data-value=\"3\">None of these<\/div><div class=\"sqp_question_hint\"><div class=\"sqp_question_hint__header\"><span class=\"spq_correct\">Correct<\/span><span class=\"spq_incorrect\">Incorrect<\/span><\/div><div class=\"sqp_question_hint__content\"><span>Correct answer is: 5, 5\u221a3, 10<br\/>On dividing the ratio 5 : 5\u221a3 : 10 by 5, we get 1 : \u221a3 : 2.
