Question 1. figure B (0, -4) Question 3. 3/2 Rectangle FGHI(x, y) (1.5x, 1.5y) endstream endobj 134 0 obj <>stream ratio of y-coordinates = 4/2 = 2 B (7.5, 3) Quadrilateral MNPQ has side lengths of 5 mm, 8 mm, 7 mm, and 4 mm. Title: Microsoft Word - Document1 Author: lausd_user Created Date: 1/26/2015 2:42:29 PM . At least one transformation must be a dilation with a scale factor other than 1, Question 6. Type below: ________. lesson 10 2 algebraic representations of dilationsmercedes financial services phone numbermercedes financial services phone number Find the angle measures of the actual sign. ________ inches Answer: ADDITIONAL EXAMPLE 1 Graph the image of rectangle JKLM after a dilation with the origin as its center and a scale factor of 2. All the explanations are given by the best maths experts. _____________, Answer: Options: The stage crewmembers calculation is incorrect. y = 3x 1 Then write an algebraic rule to describe the dilation. The center of dilation is the origin and (x, y) (3x, 3y). Sketch the image of the figure after the dilation. (x, y) -> (x +5, y-6), Question 3. dilations map a line segment (the preimage) to another line segment whose length is the product of the scale factor and the length of the preimage Dilation Property #6 dilations map a line not passing through the center of dilation to a parallel line and leave a line passing through the center unchanged k= image over preimage . _____________. Communicate Mathematical Ideas Explain what each of these algebraic transformations does to a figure. Type below: Perimeter = 8 units This is called a reduction. So, the scale factor of the dilation is 3/4. Question 13. d. A rectangular room has coordinates Q(2, 2), 6(7, 2), S(7, 5), and T(2, 5) on the blueprint. (-1, -1) Type below: If you draw a line connecting each pair of corresponding vertices, the lines will intersect at the center of dilation, Question 20. dilation with a scale factor of 0.5 (-4, -2), Question 12. Question 5. The figures are similar is they are the same shape but different size SO one is a dilation of the other, Question 11. _____________. Green square: (x, y) (2x, 2y) The coordinates of the vertices of the original image are multiplied by _1 2 Image perimeter: _________, Answer: Type below: Draw Conclusions A figure undergoes a sequence of transformations that include dilations. Question 6. What are the vertices of the dilated image? The drawing has sides measuring 6 cm, 8 cm, and 10 cm, and angles measuring 37, 53, and 90. Type below:
