Manipulate the sliders and/or input boxes to select the measurements for two angles and the length of the included side.[br][br]Slowly slide the Step slider one step at a time to see the construction unfold.[br][br]No matter what we pick for these three measurements, there is always such a triangle possible. [br](Because of the quirks of the construction, some positions may make the figure disappear.)[br][br]If two triangles have two pair of corresponding congruent angles, and the corresponding included sides are also congruent (ASA Condition), then do the triangle have to be congruent?
