Need easy way to lock size of image

do you mean to type D = Point(Circle(C, 6))?. then C for moving and D for rotating

if you want to use another points (ie: vertex of pentagon) plot them and attach the file again

I think you must redefine the black polygon if you want the pentagon inside

I have updated the file. I was trying to find a way to make it work, and might not have deleted D = Point(Circle(C, 6)) when uploaded here for advice.

The object is to get students to move the pieces to create the composite shape on the shape. It's worked to have the black outlined polygon so students can drag the other figures over it, I just don't know how to keep the size of the other polygons so they don't change, but also be able to rotate easily. To ADD to the issue, I would also like to have the option of the polygon to reflect if it can (see the blue triangle), but it's not necessary, and I can keep it so it matches up. Although part of this idea is for students to reflect/rotate/translate polygons to make a composite polygon. Thank you for your help

better if the great figure was a polygonal path created with GG.

in attached I created several points (3+5 points) then I placed them over a part of figure and created a rigid polygon for each polygon.

I do always my puzzles in this way

It is also possible to create one piece with several colours in polygonal form

I'm not sure what you mean by polygonal path (is this a command/tool of geogebra?)

I tried to understand your construction, but saw "circle" and "perpendicular" "vectors" etc, but not sure what exactly you did/how it was created. Not sure if you can give me a more precise "how-to" Thank you for taking the time.

see the help about the rigid polygon tool

https://help.geogebra.org/e...

this tool redefine a set of points using circle, point, perpendicular, polygon tools for creating a rigid shape with first point for moving and second point for rotating.

si lo deseas puedo explicarlo mejor en español, pues mi ingles es muy escaso

if you wish I can explain better in spanish

This comment is for manipulate pictures (not geometric constructions):

The easiest way (for me) to move and rotate a picture is to use the commands Move() and Rotate().

This implizit that you have 2 pictures: the (hidden) original and a visible copy, created with Rotate(Move())

In the attachment all hidden original-objects are in graphic-2 (only here its possible to change the size) and

in graphic-1 is the second object (depending/copy of original-object) that can move and rotate by a user

Thank you both for your help!
