The Dilation of a Point Calculator is a computational tool designed to determine the new coordinates of a point after undergoing dilation. Dilation involves scaling an object up or down with respect to a fixed point known as the center of dilation. The calculator uses the following formula to perform the dilation:

New_x = Center_x + (Point_x - Center_x) * Scale_factor New_y = Center_y + (Point_y - Center_y) * Scale_factor

Where:

  • Center_x and Center_y are the x and y coordinates of the center of dilation, respectively.
  • Point_x and Point_y are the x and y coordinates of the point to be dilated, respectively.
  • Scale_factor is the scale factor of the dilation. If the scale factor is greater than 1, the point will dilate away from the center; if it’s between 0 and 1, the point will dilate towards the center.

Table of General Terms

TermDefinition
DilationThe process of resizing an object while maintaining its shape.
Scale FactorA ratio that describes how much larger or smaller the dilation will be.
Center of DilationThe fixed point around which dilation occurs.
CoordinatesPairs of numbers that represent the location of a point in a coordinate plane.

Example of Dilation of a Point Calculator

Let’s consider an example to understand how the Dilation of a Point Calculator works:

Suppose we have a point with coordinates (3, 5) and we want to dilate it with a scale factor of 2 around the center (0, 0). Using the formula mentioned above, we can calculate the new coordinates as follows:

New_x = 0 + (3 - 0) * 2 = 6 New_y = 0 + (5 - 0) * 2 = 10

So, after dilation, the new coordinates of the point will be (6, 10).

Most Common FAQs

What is dilation in geometry?

Dilation in geometry refers to the transformation of an object by enlarging or reducing its size while maintaining its shape.

How do you calculate dilation?

Dilation can be calculated using the Dilation of a Point Calculator, which utilizes the coordinates of the center of dilation, the point to be dilated, and the scale factor.
