If you feel unsure about this, create a sketch and see how it works by measuring angles, etc.
This is the theorem done in class today that is also Thm. 11.1 in Bix. Do this construction with Sketchpad and transform a shape or a point by the product of rotations and see that the product is what it is supposed to be.
Do the problems in Bix 9.21 using the ideas of 2 above.
Let M be a line reflection and T be a translation. Investigate the product TM in the special case when T is perpendicular to the mirror line of M and in general.
Also, take blob and generate a pattern by repeated applications of T and M.
7. Generate a pattern with R = rotation by 90 degrees with center A and also S rotation by 90 degrees with center B.Return to Math 444 Home Page.
