In which sketching method are angles not uniform between axes?

The perspective sketching method is characterized by the representation of objects in a way that resembles human vision, where parallel lines converge at a vanishing point. This approach creates a sense of depth and realism, leading to non-uniform angles between the axes. Unlike isometric sketches, which use equal angles to represent three dimensions on a flat surface, perspective sketches depict objects with varying angles and proportions to mimic how they appear to the human eye.

In contrast, isometric sketches maintain a uniform angle of 120 degrees between axes, providing a systematic representation of three-dimensional objects. Cavalier and cabinet pictorial sketches also use uniform angles but differ from perspective sketches in their degree of foreshortening. Cavalier sketches maintain the full scale of depth while cabinet sketches typically reduce the scale of depth to give a more realistic depiction.

Thus, the nature of perspective sketches makes them the correct answer as they showcase angles that are not uniform, reflecting the variability found in real-world viewing situations.
