Task 1
Interact with this app for a couple of minutes. Be sure to move the vertices (corners) of these triangles around. Be sure to interact with the sliders as well.
Press the recycle icon (upper right corner) in the app above. Then slide the [b]Slide Me![/b] slider again slowly all the way to the right. [br][br]In this app, suppose one colored angle measures [math]120^\circ[/math]. Suppose the other colored angle measures [math]25^\circ[/math]. What would the measure of the 3rd (non-colored) angle be in each triangle?
How are the two triangles above [b]similar[/b]? How are they [b]different[/b]?
