What angle is associated with oblique projection?

1. 30 degree

2. 45 degree

3. 60 degree

4. 90 degree

The correct answer is: 45 degree

The angle most commonly associated with oblique projection is 45 degrees. This projection technique involves projecting the image at an angle to the plane of projection, which helps illustrate depth while maintaining the dimensions of the object. When a 45-degree angle is used, the object is represented in a way that allows viewers to easily understand both its shape and its three-dimensional aspect. In many cases, oblique projections utilize a specific 45-degree angle to achieve a balanced representation, making it easier for engineers and designers to convey information about the object being depicted. This choice of angle strikes a good balance between visual clarity and the representation of depth.
