A and C 4b. Reflections, translations, and rotations are all isometries. About project SlidePlayer Terms of Service. The actual answer is more than 9 servings. Dilation is a transformation that changes the size of a figure but not the shape. For example, in the first problem above, there are many different places to put the center of dilation in order to meet the constraints specified in the problem.

Step 1 Draw a line through Q and each vertex. Click below for lesson resources. Lesson leseon Problem-Solving Practice Dilations 1. My presentations Profile Feedback Log out. Submit Feedback Report Problems x. Multiply the coordinates of the original point 2, 1, called the image, by 3. Lesson problem solving dilations answers. Dilations and Scale Factors – Step-by-Step Lesson This dilation is centered at the origin, so you can find the image by multiplying the x- and y-coordinates by the scale factor.
On the transparency 1 cm represents 12 cm on the projection. Problem-Solving Application The answer is correct. Recall that a dilation changes the size of a figure by a scale factor, but does not change Sample answer: At the end of the lesson students reflect on their experiences with the activity and make connections to the types of problem solving they solging be doing for the rest of the course.
