The drawing has the hypotenuse on the bottom. (x, y) (2x, 2y) _____________, Answer: _____________, Answer: vertically stretches by a factor of 2, Question 12. Answer: -6/-3 =2; 6/3 = 2 10.2 Algebraic Representations of Dilations. . Describe the image of a dilation with a scale factor of 1. Original perimeter: 16 Options: By, definition of a dilation in which it can only be enlarged or reduced with respect to the scale factor k between 0 and 1 or greater than 1, respectively, if the scale factor in the dilation is equal to 1, then the image would be the same as the preimage. b. What are the coordinates? (-4, 4) Type below: _____________, Answer: A dilation with center (0, 0) and scale factor k is applied to a polygon. You can use dilations when drawing or designing, Question 1. Try keep it short so that it is easy for people to scan your page. A dilation takes a line not passing through the center of the dilation to a parallel line, and leaves a line passing through the center unchanged. MN = \(\sqrt{(9-4.5)^{2}+(6-6)^{2}}\) This 8th-grade geometry guided notes and activity bundle is a great way for your students to learn about solving transformations, angle relationships, and 2d views of three-dimensional models! 15/5 = 3 mm Some dilations are reductions. The position of the sketch from 12A will be 1/2 unit above the sketch obtained when the translation occurs first. Type below: AB/AB = 6/2 = 3 (x, y) (\(\frac{2}{3}\)x, y) What is the effect on the figure when k > 1? The triangles have only one pair of congruent angles, Question 2.
