IM 8.2.4 Lesson: Dilations on a Square Grid

Point [math]C[/math] is the dilation of point [math]B[/math] with center of dilation [math]A[/math] and scale factor [i][math]s[/math][/i]. Estimate[i] [math]s[/math][/i]. 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.

[size=150]What happens if the center of dilation is a point on the circle? Using center of dilation [math](0,0)[/math] and scale factor 1.5, dilate the circle shown on the diagram. This diagram shows some points to try dilating. [/size]
