Hello!

I am creating an activity on Trigonometric Functions. I want to begin by having students look at ratios from similar right triangles. To do this, I want them to be able to adjust the size of a triangle using moveable points, click a button and lock in the side lengths of the current triangle into a table. I want them to repeat this process 3 times. I’ll then be pulling those values into a different slide where we will look at the ratios.

I have the table filling in with button clicks. Currently, the triangle snaps back to the original triangle after each button click. I’d like the triangle to remain the same size it was at when they click the button until they move the points again, but not have the inserted table values change when they move the points until they click to add another row so that we can get 3 rows of values. I realize there may be a simpler way than what I’ve done (I feel I have seen something like this before with a single point, but can’t find it).

I’m not sure if I am explaining this well. Please take a look at what I have and if you have suggestions for how I can accomplish what I am trying to do, let me know.

Thank you!
