In the applet above, move the "slider" bar that is representing your scale factor. Move points A and B to see what happens to the dilation and move the center of dilation, point O.
What happens when the scale factor is bigger than one? (Select all that apply)
What happens when the scale factor is smaller than one? (Select all that apply)
No matter what your scale factor is, line segment A'B' always seems to stay ________ to line segment AB.
When the center of the dilation is a point on the figure, what happens to that point when the figure is dilated?
When the center of the dilation is somewhere on the line segment, what happens to the line segment when you dilate it, in comparison to when the center is NOT on the line segment.
It doesn't change location, just size.
In the applet above, move the points A, B, C, and O around freely. Use the slider to adjust the scale factor.
What happens to the angles when you dilate a shape?
What scale factor should be used so that triangle ABC is congruent to triangle A'B'C'?
In the applet above, move around points A, B and O. Adjust the slider to change the scale factor of the dilation, then answer the questions below:
How is dilating a line different from dilating a line segment?
Size doesn't change because it already goes on forever.
Explain what happens when you dilate a line with a center of dilation that is on the line itself.
The line lands perfectly on top of itself
What are the THREE main things that happen to something when you dilate it?
1.) It gets bigger/smaller[br]2.) It moves closer/farther from the center of dilation[br]3.) All line segments end up parallel to the original
