To ascertain one angle by utilizing another, one must apply the tenets of geometry, focusing on the characteristics of angles found in shapes such as triangles or circles. This process may require understanding of notions like supplementary angles, complementary angles, or the properties of angles in polygons. A good grasp of trigonometry could also prove beneficial.
