Dilate. When you have your eyes checked, the optometrist sometimes. dilates one or both of the pupils of your eyes. 1 ACTIVITY: Comparing Triangles in a Coordinate Plane. Work with a partner. Write the coordinates of the vertices of the blue triangle. Then write the coordinates of the vertices of the red triangle. a.
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.
In this lesson, we will look at dilations in geometry. What is dilation in geometry? 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.
Dilation Worksheets. Examples, solutions, videos, and worksheets to help Grade 7 and Grade 8 learn how to use a compass and a ruler to perform dilations. Learn that dilations map lines to lines, segments to segments, and rays to rays. Know that dilations are angle-preserving.
is a dilation? A dilation is a transformation that enlarges or reduces the size of a figure by a scale factor of k. Give the dilation rule below and draw an example of a reduction and enlargement. k (x,y) = _____ Determine the scale factor for the dilation below then state if it is an enlargement or reduction. Dilate ∆ABC by
