Example: Find the center of dilation if dilating (3, −7) by a factor 3 results in (9, −3). Let (𝑥, 𝑦) be the center of dilation. Then we have 𝑥 = (3 ∙ 3 − 9)∕(3 − 1) = 0 𝑦 = (3 ∙ (−7) − (−3))∕(3 − 1) = −9 So, the center of dilation is (0, −9)

Dilations are a way to stretch or shrink shapes around a point called the center of dilation. The amount we stretch or shrink is called the scale factor. If the scale factor is greater than 1, the shape stretches. If it's between 0 and 1, the shape shrinks.

A dilationis a transformation that produces an image that is the same shape as the original, but is a different size. (The image is similar to the original object). Dilation is a transformation in which each point of an object is moved along a straight line. The straight line is drawn from a fixed point called the center of dilation. The distance t...
We will first look at enlargements which are dilations with scale factors greater than 1 Example: Enlarge triangle PQR with O as the center of dilation and a scale factor of 2. Solution: Step 1: Measure OP. Step 2: Extend the line OP to the point P’ such that OP’ = 2OP. Step 3: Repeat the steps for all the vertices: point Q to get Q' and point R to...
If the scale factor of a dilation is between 0 and 1, the image will be smaller than the object. It is then called a reduction. Example: Enlarge triangle PQR with O as the center of enlargement and scale factor . Solution: Step 1 : Join O to P. Step 2 : Mark off the point P ’ on OP such that OP' = OP. Step 3 : Repeat the steps for all the vertices:...
If the scale factor of a dilation is negative then the image will be on the opposite side of the center of dilation compared with the object. How to create a dilation of a geometric figure using a center of dilation and a negative scale factor? 1. Show Video Lesson
We will now look at how to create a dilation on a coordinate plane. Dilations A dilation is a non-rigid transformation, which means that the original and the image are not congruent. They are, however, similar figures. To perform dilations, a scale factor and a center of dilation are needed. If the scale factor is larger than 1, the image is larger...
