What are the two types of pictorial drawings?

  1. Isometric and perspective

  2. Orthographic and oblique

  3. Top view and side view

  4. Two-dimensional and three-dimensional

The correct answer is: Orthographic and oblique

The correct answer identifies the two primary types of pictorial drawings as isometric and perspective. These drawings provide a visual representation that aids in the understanding of three-dimensional objects on a two-dimensional plane. Isometric drawings maintain scale along all three axes, allowing the viewer to perceive the dimensions of an object accurately without distortion. In contrast, perspective drawings represent objects in a more realistic way through vanishing points, which leads to the appearance of depth. This is why these two types are fundamental in technical drawing and design. Other options do not represent correct groupings of pictorial drawings. Orthographic and oblique are distinct styles of projection drawings, not pictorial types. Top view and side view are projections or views within orthographic drawing rather than pictorial representations. Lastly, two-dimensional and three-dimensional refer to dimensionality rather than specific methods or styles of pictorial drawing.
