Answer
Start by identifying the correct vanishing point (VP) indicated in the perspective drawing on the right. For the TV, radiate lines from the corner points of the TV towards the designated vanishing point. Ensure the lines are straight and clearly indicate the direction towards the vanishing point.

Answer
Using the plan view provided, project the necessary vertical and horizontal lines downwards from the corner points of the TV. These lines must extend to meet the perspective lines already drawn. This will help in accurately placing the TV in perspective.

Answer
From the projected lines on the stand, determine the mid-section and project additional lines that will help visualize the height and width of the mid-section of the stand. Use light pencil marks until you are satisfied with the proportions.

Answer
Finalize the drawing by enhancing the clarity of lines and outlines. Erase any unnecessary marks and add shading if required to denote volume and weight. Ensure the drawing is neat and legible to enhance its presentation quality.
