G.CO.4 Exploring Translations 4
Question 4
a) Describe how the object is translated. Is the image congruent to the pre-image?
Question 4 and a little bit more
Now click the line 
tool. Draw a line connecting point A on the preimage to its corresponding point A on the image by clicking both points. If you make a mistake, first select the select 
tool and then click the reset 
button in the top right (it's a bit finicky, so you may have to click it more than once to get it to work).
What is the slope of the line?
Question 4 and even more
Connect the rest of the points on the preimage to their corresponding points on the image (B to B, C to C, and D to D) using the line 
tool. What are the slopes of the rest of the lines?
What did you notice about the lines? Do they ever intersect? There's a name for these kind of lines... Pay attention to the slopes, that will be important later.
