What It Is:
This is a geometry worksheet focusing on dilations. The worksheet contains four separate problems. Each problem shows a shape on a coordinate plane and instructs the student to draw the dilated image. Two problems require dilation by a factor of 2, and two require dilation by a factor of 1/2, all using the origin (0,0) as the center of dilation.
Grade Level Suitability:
This worksheet is suitable for grades 7-9. It requires an understanding of coordinate planes and the concept of dilations, which are typically introduced in middle school geometry.
Why Use It:
This worksheet provides practice in performing dilations of geometric figures on a coordinate plane. It reinforces the understanding of scale factors and how they affect the size of a shape. It also helps students visualize the effect of dilations on the coordinates of points.
How to Use It:
Students should plot the original shape on the coordinate plane, then calculate the coordinates of the dilated image by multiplying the original coordinates by the given scale factor (2 or 1/2). Finally, they should plot the new points and draw the dilated image.
Target Users:
This worksheet is suitable for students learning about geometric transformations, specifically dilations. It can be used for classwork, homework, or as a review activity. It is also useful for students who need extra practice with coordinate geometry.
