Answer :
Final answer:
In third angle projection, the image planes are located between the object and the observer, important for representing three-dimensional objects in engineering and technical drawings. Correct answer is option A.
Explanation:
In third angle projection, the image planes are imagined as lying between the object and the observer. This method of projection is commonly used in engineering and technical drawings, where three orthographic views (front, top, and right side) are typically arranged in a specific way around the object to represent the three dimensions accurately. The observer's perspective is as if they are looking at each plane from the outside, which is opposite compared to first angle projection where planes are visualized as if the observer is looking through them from the inside.
