How do you calculate dilation?

[organicbird383]

Starting with ΔABC, draw the dilation image of the triangle with a center at the origin and a scale factor of two. Notice that every coordinate of the original triangle has been multiplied by the scale factor (x2). Dilations involve multiplication! Dilation with scale factor 2, multiply by 2.

To create an enlargement with a scale factor of 2: Draw straight lines connecting each vertex to the center of dilation. Use the compass to find the points that are twice the distance from the center of dilation as the original vertices. Connect the new vertices to form the dilated image.

Similarly, whats the opposite of dilation? Theres no single word. The usual phrase is constricted pupils. Incidentally, in fiction people whove taken heroin or related drugs are almost inevitably described as having dilated pupils even though the described drugs cause constriction!

In respect to this, how do u find the scale factor?

To find a scale factor between two similar figures, find two corresponding sides and write the ratio of the two sides. If you begin with the smaller figure, your scale factor will be less than one. If you begin with the larger figure, your scale factor will be greater than one.

What are the properties of dilation?

A dilation is when a shape has kept its orientation but has been changed in size, either getting smaller or getting larger. This is a form of transformation, which is a repositioning of a shape. There are four basic transformations: reflection, rotation, translation, and dilation.
