Hello,
I am building this activity for my class and want to have check sign when students correctly answer all of the questions. Unfortunately that is not working.
Activity works for triangle, quadrilateral, and pentagon. I am new to CL and still trying to figure out the logic behind objects. The way I did it is that each type of polygon has its own graph and table to check for values. When polygon is selected by type other windows are hidden and made readonly. Anyways, when all data is entered I instead of x that is shown while not finished see just a dot and I would like check sigh that I always have on other activities.
Any suggestion is welcome.
Thank you.
I’m not sure where your issue is, but I have a few tips that might simplify things.
Define lists of points, then you can use the list for the pre-image, and with a scale factor variable, define the image.
Also rather than conditionally displaying components, conditionally display using one graph.
Say for the triangle:
n=3 #number of vertices
T=[(1,1),(3,1),(2,3)] #list of vertices
k=5 #scale factor, but define it in the CL
polygon(T{n=3}) #the preimage
polygon(k*T{n=3}) #the dilated image
I jumped into this headlong, but I have other work to do and don’t know that I’ll finish in time to be useful to you.

Here’s my version:
You may want to change the conditions for some of the buttons.
If you turn on the folders for each individual polygon, you can move the points to where you want.
Thank you, this looks awesome. I was trying to make a model to use only one graph and just add points. Only question that I have is that I would like to be able to change points coordinates from CL and use the same slide with different shapes.
Is there any way that I could change table constant coordinates from CL of graph window and how would it look. I see that table is defined as a list, but do not know how to address proper row. I am new in this kind of programming.
Thanks.
You’d need to not use the tables and go back to sliders. For what reason did you want the CL to control the coordinates, may I ask?
I usually make a template screen with a few different variations on one screen, then I copy this template screen and change parameters creating different tasks for students. When one parametric screen is created, I can make individual assignments for students who need more practice.
Again I am new to CL coding and desmos activities and any help or suggestion is welcome. I will share what I learn and know as I go.
Thank you for your support.
Okay. I just made the tables, so that they are all draggable points, but you could just create lists with whatever variable names you want to use in the CL.
x_1=[a,b,c]
Just note that if you’re using different polygons, list V has a little trickery to make equal length lists for the grading portion.
