What geometry concept is dynamically being illustrated in the applet below? [br]Feel free to move any 1 (or more) of the [b][color=#444444]gray points[/color][/b] anywhere you'd like.
[b]One Method of Constructing an [color=#38761d]Isosceles Triangle[/color][/b] [b]via Compass and Straightedge[br][br][/b]Since radii of the same circle are always congruent, the triangle formed has at least 2 congruent sides. Since [color=#38761d][b]an isosceles triangle is a triangle with at least 1 pair of congruent sides[/b][/color], the triangle formed is an [color=#38761d][b]isosceles triangle[/b][/color].
