Lets look at the value of each combination. H first H=.50*.75=.375 HH=.50*.50*.75.=.1875 HS=.50*.75*.50=.1875 S first S=.75*.5=.375 SH=.25*.5*.75=.09375 SS=.25*.75*.50=.09375 so, check my calcs. It seems H first, then either second is the best strategy.

A student asks whether a polygon whose sides are congruent is necessarily a regular polygon and whether a polygon with all angles congruent is necessarily a regular polygon. How do you answer?

How do YOU respond? Angles do not depend upon the length of the rays. They measure the difference in direction between the two lines (rays).

Point symettry is oft called rotational symettry. Things can be rotated x degrees, and the image is the same. Examples: http://www.mathsisfun.com/geometry/images/king-of-hearts.jpg THe letters X, I, have point symettry, they can be rotated 180 degrees. They also have plane ...
