If you have a blood ketone meter, this is what the readings mean: 1  Light Ketosis: 0.5 mmol/L â 0.8 mmol/L. 2  Medium Ketosis: 0.9 mmol/L â 1.4 mmol/L. 3  Deep Ketosis (best for weight loss): 1.5 mmol/L â 3.0 mmol/ L.
(3) Symmetry, in the general sense, means the invariance of the structure of a mathematical or physical object with respect to transformations of the object. For example, the symmetry of the laws of the theory of relativity is determined by their invariance with respect to the Lorentz transformations.1) A symmetry, in the narrow sense, is a reflection with respect to a plane Î± in space or with respect to a line a in the plane. Such a symmetry is a transformation of space or the plane that takes every point M into a point Mâ such that the line segment MMâ is perpendicular to Î± or a and is divided in half by Î± or a.
Line Symmetry. Basically, a line of symmetry is a line that divides a figure into two mirror images. The figure is mapped onto itself by a reflection in this line. A set of points has line symmetry if and only if there is a line, l, such that the reflection through l of each point in the set is also a point in the set.(May also be referred to as reflectional symmetry.). Certain figures can be mapped onto themselves by a reflection in their lines of symmetry.asically, a figure has point symmetry when it looks the same when up-side-down, (rotated 180Âº), as it does right-side-up. The number of positions in which the rotated object appears unchanged is called the order of the symmetry.
