For this activity, we will be dragging the pink points around to see what happens to the angles α, β, and γ as well as what we can observe.[br][br]Questions[br][br]What do you notice about the sum of all three angles? Does this hold true for [b]any [/b]shaped triangle?[br]Do the lengths of the edges matter? Why / why not?[br]Is it possible to have two 90° angles in one triangle?[br][br]*Quickfire Challenge!* [br][br]Let us hide one of the angles and see if you can work out the missing angle!
