- dilation with a scale factor of 1 2 and centered at point A. Is triangle ABC congruent to triangle A'B'C'? Explain your answer. 11 Triangle QRS is graphed on the set of axes below. On the same set of axes, graph and label Q'R'S', the image of QRS after a dilation with a scale factor of 3 2 centered at the origin. Use slopes to explain why Q'R' QR.
- Step 1: This dilation is centered at the origin, so you can find the image by multiplying the x- and y-coordinates by the scale factor. Multiply the coordinates of point A(0, 0) by 2. The image is A ′ (0, 0).
Desmos offers best-in-class calculators, digital math activities, and curriculum to help every student love math and love learning math.
- Transformation Matrices. The above transformations (rotation, reflection, scaling, and shearing) can be represented by matrices. To find the image of a point, we multiply the transformation matrix by a column vector that represents the point's coordinate.
👍 Correct answer to the question Find the image of (2,3) under a dilation with center at the origin and a scale factor of -3. the coordinates of the image are - ehomework-helper.com
- Graphing Enlargements. When a dilation in the coordinate plane has the origin as the center of dilation, you can find points on the dilated image by multiplying the. x- and y-coordinates of the original figure by the scale factor. For scale factor k, the algebraic representation of the dilation is (x, y) → (kx, ky). For enlargements, k> 1.
Dilation with Center at Origin | Dilation Worksheets. Dilation Worksheets - Center at Origin. Dilation is a transformation, that stretches or shrinks the original figure presented on the grid based on the scale factor.

ImageJ can be used to recover numeric coordinate data from scanned line graphs using the following procedure. Steps 1-6 are not necessary for binary (black and white) graphs. For practice, use the File>Open Samples>Line Graph sample image. Open the image containing the graph. Open the thresolding tool (shift-t).
- Since the scale factor is 2, the corresponding point in the image B' is twice that distance from O and lying on the same line, so OB' is 2 times 12, or 24. Note that if the scale factor is less than 1, then the image points are closer to the center of dilation to create an image smaller than the original. Draw the dilation with a scale factor of 1.5.
The distance from the center of dilation to the vertex of a figure is then multiplied by a number, called the scale factor, to produce the dilated image. • If the scale factor is greater than 1, the dilation will enlarge the original figure. • If the scale factor is between 0 and 1, the dilation will shrink the original figure.
