Lay a ruler at one end and increase the line by two lengths dilation by a factor of 3.
How to dilate a triangle. Scroll down the page for more examples and explanations of dilations. This analogy can be extended to any number of real world objects or even a line on a paper. Graph the triangle ABC with coordinates A2 6 B2 2 C6 2.
Next we multiply each coordinate by the scale factor of 12. The preimage of triangle ABC is dilated with respect to point O by a scale factor of to produce the image of triangle DEF. We are told the triangle n prime is the image of triangle n under a dilation so this is n prime and in this red color and then n is the original and is in this blue color what is the center of dilation and they give us some choices here choice a B C or D as a center of dilation so pause this video and see if you can figure it out on your own so.
Lets see how to dilate a point about a point other than the origin with this next example. Starting with ABC draw the dilation image of the triangle with a center at the origin and a scale factor of two. Use the interactive transformation tool to perform dilations.
Then dilate the image by a scale factor of 12 with the origin as the center of dilation. The following diagrams show the triangle ABC dilated with different scale factors. Draw straight lines connecting each vertex of the image to the center of dilation.
Its going to be a reduction because when you multiply something lower than one you get a smaller number. Use the compass to find the middle of each segment between the vertices and the center of dilation. When it comes to dilations there are different types of questions we may be faced with.
Next we multiply each coordinate by the scale factor of 12. Dilation with scale factor 2 multiply by 2. Notice that every coordinate of the original triangle has been multiplied by the scale factor x2.
First we graph our original triangle in the coordinate plane. How do you dilate a triangle with a scale factor of 2. We say that triangle PQR is transformed onto triangle PQR by a dilation with center at O and scale factor.
Subsequently question is how do you dilate 2 pictures. Dilation with scale factor 2 multiply by 2. Dilating about a Point other than the Origin.
Triangle PQR is a dilation of triangle PQR. We will first look at enlargements which. Dilation with scale factor 1.
Dilation with scale factor 2 multiply. First we graph our original triangle in the coordinate plane. You multiply each of the coordinates in the coordinate plane by 12.
In the video Sal dilates the triangle under a scale of 12. Also points on triangle DEF are the distance from O relative to their corresponding points on triangle ABC. Starting with ABC draw the dilation image of the triangle with a center at the origin and a scale factor of two.
