Dilation is a transformation that alters the size of a figure while maintaining its shape and proportional relationships. It involves expanding or contracting the figure around a fixed point called the center of dilation, using a scale factor that determines the degree of enlargement or reduction. This geometric operation preserves the angles and the relative positions of points within the figure.

What is the word for imperfect dilation?

The term for imperfect dilation is "hypodilation." It refers to a condition where dilation does not occur fully or adequately, which can affect various physiological functions, such as the dilation of blood vessels or pupils.


What does the word dilation in geometry mean?

Getting bigger. Dilation factor of 2, then it would get twice the size.


What are the invariant points of a dilation?

Invariant points of a dilation are the points that remain unchanged under the transformation. In a dilation centered at a point ( C ) with a scale factor ( k ), the invariant point is typically the center ( C ) itself. This means that when a point is dilated with respect to ( C ), it either moves closer to or further away from ( C ), but ( C ) does not move. Therefore, the only invariant point in a dilation is the center of dilation.


How can you determine whether a dilation's is a reduction or a enlargement?

To determine whether a dilation is a reduction or an enlargement, compare the scale factor to 1. If the scale factor is greater than 1, the dilation is an enlargement, as the image will be larger than the original. Conversely, if the scale factor is between 0 and 1, the dilation is a reduction, resulting in a smaller image. Additionally, you can observe the distances from the center of dilation; if they increase, it's an enlargement, and if they decrease, it's a reduction.
