Half round syemmtry blocks

Purpose:

The props Half round syemmtry blocks used to determine the number

Half round syemmtry blocks a flat wake.

How to use

1. Square

Consider the square area of the model is made of plastic in a frame in

the picture above. When the square was stabbed in the model P, then rotated

the square area was out of the frame. After playing 1800 (half round) square

area it goes back into the frame, with a dot in the corner of B. The same steps

are always done up to this point “a” return to the original position at point

“A”. Until we know how many symmetries that exist in a half round square.



2. Rectangle

Consider the rectangle area of the model is made of plastic in a frame

in the picture above. When the rectangle was stabbed in the model P, then

rotated the rectangle area was out of the frame. After playing 1800 (half round)

rectangle area it goes back into the frame, with a dot in the corner of B. The

same steps are always done up to this point “a” return to the original position

at point “A”. Until we know how many symmetries that exist in a half round

rectangle.



3. Equilateral triangle

Consider the model in the equilateral triangle, which is made of plastic

in a frame in the picture above, When the equilateral triangle was stabbed in

the model P, then rotated the equilateral triangle area was out of the frame,

after playing 1800 (half round) equilateral triangle area it goes back into the

frame, with a dot in the corner of B.The same steps are always done up to this

point “a” return to the original position at point “A”. Until we know how many

symmetries that exist in a half round equilateral triangle.

4. Isosceles triangle



Consider the model in the Isosceles triangle, which is made of plastic in

a frame in the picture above, When the Isosceles triangle was stabbed in the

model P, then rotated the Isosceles triangle area was out of the frame, after

playing 1800 (half round) Isosceles triangle area it goes back into the frame,

with a dot in the corner of B.The same steps are always done up to this point

“a” return to the original position at point “A”. Until we know how many

symmetries that exist in a half round Isosceles triangle.
