Using knowledge from the first reflection activity, reflect the pre-image across the line of reflection. Note: Their may be tools you do not have to use in this activity.
1. What is the relationship between the line of reflection and the segments connected to the corresponding vertices of the pre-image and image? 2. Follow the steps to construct the image: a. Construct perpendicular lines from vertex A of the pre-image to the line of reflection. b. Construct the point of intersection of the two lines. This should be named Point D. c. Draw a line segment connecting Vertex A and Point D. You should see the measure of the line segment in the Algebra View on the left. 3. What is Point D in relation to the line segment AA'? 4. Consider the tools you have not used. What do you still need to draw to construct A'? a. After constructing A', check with your teacher to make sure you are correct. b. If you are correct, repeat Steps 2A-4A for the other two vertices. 5. Make a polygon. a. Check with your teacher to make sure you are correct. b. If given the ok, delete the object and change the line of reflection. c. Repeat the process.
