As exercise physiologist Harry Pino tells io9, muscle cells don't actually convert into fat, which is a common myth. What really happens is that the muscle cells - which are completely different than fat cells - become smaller, because now you donât have a demand of power and strength - theyâre not growing, he says.
The composition of two reflections across two parallel lines is equivalent to a translation. The translation vector is perpendicular to the lines. The length of the translation vector is twice the distance between the lines. The composition of two reflections across two intersecting lines is equivalent to a rotation. The center of rotation is the intersection of the lines. The angle of rotation is twice the measure of the angle formed by the lines.
Reflect shapes in the lines y = x and y = -x. Reflection is taking the mirror image of a shape, where the mirror line is called the line of symmetry. The mirror line does not have to be horizontal or vertical, it can also be diagonal. You can use tracing paper to help you draw the mirrored shape. Reflection in the y=x swaps the x and y co-ordinates.
