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 ...
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.
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.

a. Dilate ABC using a scale factor of 2 and a center of dilation at the origin to form A ′B′C ′. Compare the coordinates, side lengths, and angle measures of ABC and A ′B′C ′. Sample Points. A(2, 1) B(1, 3) C(3, 2) Segments. AB = 2.24. BC = 2.24. AC = 1.41. Angles. m∠A = 71.57°. m∠B = 36.87°. 1 b. Repeat part (a) using a scale factor of — .
