WebVerify that dilations result in congruent angles and proportional line segments. G.SRT.A.2 4 Divide a line segment into equal sections using dilation. G.CO.D.12 G.SRT.A.1.A G.SRT.A.1.B 5 Dilate a figure from a point on the figure. Use the properties of dilations with respect to parallel lines to verify dilations and find the center of dilation. WebTo determine the coordinates of the dilated point, add the horizontal and vertical distances to the x- and y-coordinates of the center of dilation: (x', y') = (c + a (x - c), d + a (y - d)) Example: Dilate triangle ABC given vertices A (-1, 0), B (-1, 3), and C (1, -3), scale factor of 2, and a center of dilation of O (-4, -5).

WebTopic 7 Similarity Lesson 7-1 Dilations Objectives: Students will be able to dilate figures on and off the coordinate plane and understand how distances and lengths in a dilation are related to the scale factor and center of dilation. Essential Understanding: A dilation is a transformation that preserves angle measure but not length. The dilation of a figure is … WebA dilation is a type of transformation that changes the size of the image. The scale factor, sometimes called the scalar factor, measures how much larger or smaller the image is. … in which quadrant does point t −5 10 lie
