obtained by connecting three points on the same plane with straight lines. <br><br>\r\n\r\n      The three points are called vertices of the triangle, and three straight lines\r\n      connecting these points are called sides of the triangle.\n    </p>\r\n    <h3 ref=\"intro\">\n      Area of a Triangle\n    </h3>\r\n    <br>\r\n    <p>\n      The area of a triangle is the span of the region enclosed between the three sides of the triangle.\r\n      <br> <br>\r\n      For a triangle with height \\(h\\) and base \\(b\\), the area is given by\r\n      $$A = \\frac{1}{2} \\times b \\times
