Check Angle Animation

Questions

Hi!
I can’t get the 2nd angle to animate when the button is pressed.

Thanks in advance for any help on this!

Here’s what I envision:

  1. Students move the slider to the given angle (in red)
  2. That line stays there, and when the button is pressed:
    a new angle will grow/animate to their given angle.

Here, I think this is what you want. I also made some changes to the way the angle was being drawn, because using that large list was causing lag. I changed it to a parametric in terms of r and theta. I also made it so they could move the angle using a rotating dot instead of the slider (wasn’t sure if you want that or not - you can hide the point and show the slider if you prefer). Let me know if you have any questions or if it’s not what you are looking for.

Yes! That’s exactly what I was looking for!
Thank you VERY much! Thanks for adding a check mark too. :slight_smile:

One more thought…
Is it simple to switch which side the angle starts on? (clockwise vs counter-clockwise)
Or possibly just another screen, with one that goes the other way.
I’d like to pose questions with angles that start both on the left and right.
Thanks!

Yes, that was easy enough to change. I made a second slide and just reversed the part of the angle that was showing. I also fixed the bounds on both slides that was preventing the dot from going all the way down since it was off the screen.

Awesome!
I thought it could be a fairly simple addition. Thanks!
Thanks for the added touch with the subtitle to read the target angle!

Here’s the finished lesson, if ya wanna see how I put your help into action for my 4th graders.
The next lesson will include angles to start on both the left and right. :slight_smile:
