First, draw a circle with a radius calculated based on the side length (side length ( s = 25 ) mm).<\/li>\n\n\n\n<li>Find the center of the pentagon and draw the 5 equal sides, ensuring the correct angles between them (108\u00b0 for each internal angle in a regular pentagon).<\/li>\n<\/ul>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Second Projection (Front View):<\/strong><\/li>\n<\/ol>\n\n\n\n<ul class=\"wp-block-list\">\n<li>In the front view, the pyramid\u2019s axis is inclined at 60\u00b0 to the HP. This means the axis is represented as slanted at an angle to the ground.<\/li>\n\n\n\n<li>The apex of the pyramid (top point) will be above the center of the pentagonal base, and its distance from the base will be represented by the axis length (60 mm).<\/li>\n\n\n\n<li>Draw the axis line at a 60\u00b0 angle to the horizontal line of the base in the front view. The height of the pyramid (60 mm) will be shown vertically along this axis.<\/li>\n\n\n\n<li>The edges of the pyramid from the apex to the base vertices will also be drawn, making sure they converge at the apex.<\/li>\n<\/ul>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Final Details:<\/strong><\/li>\n<\/ol>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The edges connecting the apex to the base vertices are shown as lines in the front view.<\/li>\n\n\n\n<li>In the top view, the pentagonal base will be seen clearly, and the apex will be directly above the center of this base.<\/li>\n\n\n\n<li>Marking the axis properly at a 60\u00b0 angle from the HP will help in creating a clear perspective of the pyramid\u2019s shape.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Explanation:<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Top View (Plan):<\/strong> In this view, we see the regular pentagon as the base.
