A dilation is a transformation in which a fi gure is made larger or smaller with respect to a point called the center of dilation. EXAMPLE 1 Identifying a Dilation Tell whether the blue fi gure is a dilation of the red fi gure. b. The fi gures have the same size and shape. The red fi gure slides to form the blue fi gure. So, the blue fi ...
Dilating a Figure in the Coordinate Plane. Graph quadrilateral KLMN with vertices K( −3, 6), L(0, 6), M(3, 3), and N( and its image after a dilation with a scale factor of . 1 −3, −3) — 3. SOLUTION. Use the coordinate rule for a dilation with 1 k. =. — 3 to fi nd the coordinates of the vertices of the image.
Dilation changes the size of the shape without changing the shape. DILATION When you go to the eye doctor, they dilate you eyes. Let’s try it by turning off the lights. When you enlarge a photograph or use a copy machine to reduce a map, you are making dilations.
Geometry Worksheet Dilations. 1. Use the ruler to draw the image of the figure under a dilation with center M and the scale factor k indicated.
Graph the image of the figure using the transformation given. 1) dilation of 2 about the origin. 3) dilation of. 5) dilation of. 2) dilation of 1.5 about the origin. 7) dilation of 1.5 about the origin K(-2, -2), L(0, 3), M(2, -2) y. x. 9) dilation of 1.5 about the origin Y(-1, 1), X(1, 3), W(2, -2)
Label the center of dilation. Dilations Answer (B)
A dilation is a transformation in which a fi gure is enlarged or reduced with respect to a fi xed point C called the center of dilation and a scale factor k , which is the ratio of the lengths of the corresponding sides of the image and the preimage.
