Your Rigid Motion packet will be due at the end of class on Monday.
The instructions you include for each problem should be precise and written using the equation editor within GSP.
Precise Instructions: Take Triangle ABC and rotate it 90 degrees around point A.
Not Precise: First I made a triangle by connecting 3 line segments. Then I labeled the vertices A, B, and C.
Tomorrow the tech crew will be installing Geometer’s Sketchpad on your laptop.
Please bring a fully charged laptop with you to class so that we can explore this awesome tool!
As you complete the Four Situations worksheet tonight, please take a moment to write about WHY the four equations fit each situation. Pay close attention to the STRUCTURE of the equations.
Tonight, please complete problems 1 – 5 on the worksheet Ten Situations.
Be sure to label your axes with specific variable names.
Be sure to come to class tomorrow with (at least) 10 quantitative variables for 3 of the situations on the Making Decisions I worksheet.
We will use these variables to build functions in class tomorrow!
Please complete the following problems over the weekend:
Today in class we began to dilate shapes without using the coordinate plane.
Please continue to extend your study with questions 6 – 87 through 90.
Tonight please answer the following questions about translations and dilations for homework:
6 – 66, 6 – 67, 6 – 78, 6 – 80
When you multiply both the x and y coordinate by the same number, that number is called a scale factor. The new image is called a dilation.
When you only multiply the x OR y coordinate by a number, then you are performing a vertical/horizontal stretch/shrink. The new shape is not a dilation, as it is not similar to the original shape.
Your homework tonight was problems 6-58 and 6-59.
You can use the following links to help you with problems 43, 46, and 47:
Please complete problems 46 – 50 (skip 47) tonight for homework!
