Hello! I’m trying to create an activity in which my students can discover that the measure of the central angle is equal to the measure of its intercepted arc. The issue I’m running into is that I can’t figure out how to get the arc measure to display on the circle. I don’t see a way to label it using the actual arc measure, so I’m trying to just label it using the measure of the central angle, but I can’t figure that out either. If anyone can help me figure out how to get the label the way I want it, or help me figure out a work around, I would greatly appreciate it!
And just to clarify my picture, I played around with “tricks” to get the angle to display. The 145° that you can see on the arc currently is actually just a reflection of the angle. It’s not pretty, and it’s not going to work for when I try to get the intercepted arc of an inscribed angle…
The geometry component is really limited in the things you can label dynamically, but here’s a version that uses the graphing calculator if its helpful Graphing Calculator
