A. The given figure is a triangle as it has three straight sides and is a closed figure.<\/p>\n\n\n\n<p class=\" eplus-wrapper\">B. The shape is not a triangle as it has four sides.<\/p>\n\n\n\n<p class=\" eplus-wrapper\">C. The shape is not a triangle as it is an open figure with three open sides.<\/p>\n\n\n\n<p class=\" eplus-wrapper\">Q. The perimeter of the triangle PQR is 16cm and the sides PQ and QR measure 4cm and 6cm. Find the length of the third side of the triangle.<\/p>\n\n\n\n<p class=\" eplus-wrapper\">Ans. We know that, Perimeter of a triangle = (Sum of all sides of the triangle)<\/p>\n\n\n\n<p class=\" eplus-wrapper\">So, the Perimeter of \u25b3PQR= PQ + QR + RP<\/p>\n\n\n\n<p class=\" eplus-wrapper\">16 = 4 + 6 + RP<\/p>\n\n\n\n<p class=\" eplus-wrapper\">RP= 16 &#8211; 10 = 6cm<\/p>\n\n\n\n<p class=\" eplus-wrapper\">So, the length of the third side is 6cm.<\/p>\n\n\n\n<p class=\" eplus-wrapper\">Q. Angles A and B of a triangle ABC measure 70\u2070 and 60\u2070, respectively. Find the third angle C.<\/p>\n\n\n\n<p class=\" eplus-wrapper\">Ans. We know that the sum of all angles of a triangle is 180\u2070.&nbsp;<\/p>\n\n\n\n<p class=\" eplus-wrapper\">So, \u2220A + \u2220B + \u2220C = 180\u2070<\/p>\n\n\n\n<p class=\" eplus-wrapper\">70\u2070 + 60\u2070 + \u2220C = 180\u2070<\/p>\n\n\n\n<p class=\" eplus-wrapper\">\u2220C = 180\u2070 &#8211; 130\u2070 = 50\u2070<\/p>\n\n\n\n<p class=\" eplus-wrapper\">The third angle of the triangle measures 50\u2070.<\/p>\n\n\n\n<p class=\" eplus-wrapper\">Q. Is it possible to form a triangle with sides measuring 2cm, 3cm, and 6cm?<\/p>\n\n\n\n<p class=\" eplus-wrapper\">Ans. To form a triangle, the sum of any two sides should always be greater than the third side.<\/p>\n\n\n\n<p class=\" eplus-wrapper\">For the given measurements, 3cm + 6cm = 9cm is greater than 2cm, 6cm + 2cm = 8cm is greater than 3cm, but 2cm + 3cm = 5cm is lesser than 6 cm. So, the given measures cannot form a triangle.<\/p>\n\n\n\n<p class=\" eplus-wrapper\">Q. If the area of a triangle is 20cm and the length of its base is 5cm, find the triangle&#8217;s height.<\/p>\n\n\n\n<p class=\" eplus-wrapper\">Ans. We know that, Area of a triangle= \u00bd x base x height<\/p>\n\n\n\n<p class=\" eplus-wrapper\">So, 20 = \u00bd x 5 x height<\/p>\n\n\n\n<p class=\" eplus-wrapper\">Height of the triangle= (20 x 2) \/ 5 = 8cm<\/p>\n\n\n\n<h2 class=\"eplus-wrapper wp-block-heading\" id=\"7-practice-problems-on-triangle\">Practice Problems On Triangle<\/h2>\n\n\n\n<p class=\" eplus-wrapper\"><div
