Wednesday 4/2

In class today we learned how to reflect objects about the lines y = x and y = -x with Notes #57.

Be sure to compare your notes from class with the ones posted here to ensure you'll be ready for Friday's quiz. There was a lot to copy - be thorough!

Homework #100: Perform the following transformation combinations:

1. Start with the point A at (-3, -1). Reflect that point across the line y = x. Now rotate that point 90º clockwise about the origin. Now translate that point +6 horizontally and -2 vertically. Give the coordinates of the newest point.
2. Figure ABCD has points at A (-2, 3), B (-4, 0), C (-3, -5), and D(0, 1). Rotate ABCD 180º clockwise about the origin. Now translate that image -3 horizontally and -5 vertically. Finally, reflect that image about the line y = -x. Give the coordinates of the new vertices.
