2. Three line segments from the letter N. Rotate the letter N counterclockwise around the midpoint of segment BC by 180 degrees. Describe the result. (I just need a simple explanation for this problem so I can understand, please!)
90° counter-clockwise gves us
D C
B A
Join DC BC BA
Another 90° counter-clockwise gives us
C A
D B
Again, join DC BC BA
In essence......rorating 180° clockwise would give us the same result !!!!
