On Geogebra make a polygon and create a line that does not go through the polygon. Take a screenshot and post it here.
Now go down to transformations and click on “Reflect about a line”. You will then click on the polygon for the object and the line. Take a screenshot and post it here.
Move the line around. Move the original polygon around. Write down 2 things you notice and 1 thing you wonder about reflections.
Click on the Segment tool under Basic Tools.
Connect a line segment between the corresponding points for the original and reflected shape. Take a screenshot and post it here/
What do you notice about the line segments?
On Geogebra make a polygon and a point outside the polygon. Take a screenshot and post it here.
Now go down to transformations under the “more” menu. Click on Dilation from a point. Click on your polygon for the object, then your point outside the polygon, and choose a scale factor. Take a screenshot and post it here.
Write down 3 things that you notice and 2 things you wonder about what the dilation does to the polygon.
Now add lines that go through the center point and a point on the polygon. Add a different line for each point. Take a screenshot and post it here.
Now do another dilation (Pick a different number than 2 or 3 since that was used in the video). Take a screenshot and post it here.
Write down 2 things you notice and 1 thing you wonder about dilations.
Now explore with differ scale factors. Pick a negative number. What do you notice?
Now pick a decimal number between 0 and 1. What do you notice?
