distance
Properties such as parallelism, ratio of distances, and the measure of angles are preserved under dilation. This means that parallel lines remain parallel after dilation, the ratio of lengths between corresponding points remains constant, and angles maintain their measures before and after dilation.
All angles are preserved. The sequence of line segments is preserved.
A isometry is a transformation where distance (aka size) is preserved. In a dilation, the size is being altered, so no, it is not an isometry.
direction
Volumetric dilation is the expansion of a material in all directions when heated. This process is significant because it can lead to changes in the material's properties and dimensions, affecting its overall behavior and performance.
Dilation
Dilation
The procedure for dilation of the kidney?
Atropine is used in ophthalmology as well when the measurement of eye refractive errors (i.e., cyclopegia) is required, due to its papillary dilation properties.
The opposite of dilation in math is contraction
Dilation (or enlargements require a centre of dilation (or enlargement). Since none has been given, no dilation is possible.
Arteriole dilation is an increase in the diameter of a small artery.
