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.
In case of a two dimensional plane, two intersecting lines are said to be perpendicular lines if they intersect at right angles. In the figure, the lines $\overleftrightarrow{AB}$ and $\overleftrightarrow{CD}$ are perpendicular to each other intersecting at the point P. We can write.ase 3: Two lines are parallel and there is no intersection. Case 4: The two lines are not parallel, but there is no intersection. Such lines are called skew lines. If P(x, y, Z) is the intersecting point of the two line segments, it will be on both the line segments.
