Mark the position of the spectator point, which is 3.3m from corner A. Draw the picture plane tangent to corner A.

Identify the vanishing points for the perspective drawing. These are generally located to the left and right of the viewer's perspective, equidistant from the picture plane.

Draw the ground line at the bottom of your drawing. Place the horizon line 3.0m above the ground line. Mark the previously identified vanishing points above this line.

Draw projection lines from the corners of the base of the pyramid to the spectator point. Ensure that the lines converge at the vanishing points.

Use the projection lines to establish the perspective of the base edges of the pyramid in your drawing.

Using the measured height, project the top vertex of the pyramid upwards from the base perspective to create a height that aligns with the viewer's perspective.

Connect the top vertex of the pyramid to the base edges already established, forming the complete outline of the pyramid.

Identify the inclined lines created by the edges of the pyramid and project these lines to the vanishing points to show correct perspective.

Draw horizontal lines at various heights of the pyramid and project these to the vanishing points from the viewer's perspective.

Draw the flag shape, an equilateral triangle, ensuring that the proportions and angles are accurate in the perspective view.

Draw the vertical pole for the flag directly beneath the triangular flag shape, ensuring it aligns with the perspective drawing.

Ensure that the vertical pole appears consistent in perspective by geometrically projecting it to ensure it appears at the correct angle and height.

Draw the inclined edges of the triangular flag, using auxiliary vanishing points as necessary to illustrate the correct angles and slopes.
