IM 8.2.4 Lesson: Dilations on a Square Grid
Point is the dilation of point with center of dilation and scale factor . Estimate . Be prepared to explain your reasoning.
Find the dilation of quadrilateral ABCD with center P and scale factor 2.
Find the dilation of triangle QRS with center T and scale factor 2.
Find the dilation of triangle QRS with center T and scale factor 1/2.
Match number cards with letter cards. One of the number cards will not have a match. For this card, you’ll need to draw an image in the next app.
One of the number cards will not have a match. Draw the image here.
The image of a circle under dilation is a circle when the center of the dilation is the center of the circle.
What happens if the center of dilation is a point on the circle? Using center of dilation and scale factor 1.5, dilate the circle shown on the diagram. This diagram shows some points to try dilating.
