👉 Undiametrically, a term used in geometry and trigonometry, refers to the relationship between two angles that are not equal but differ by an angle of 90 degrees. This means that one angle is greater than or less than the other, but they are not exactly the same. For example, if you have two angles A and B, where angle A is greater than angle B, then we can say that angle A is "undiametrically" greater than angle B because
