In the applet below, use the tools of transformational geometry to informally demonstrate the SAS Triangle Theorem to be true. [br][br]That is, use the tools of transformational geometry to map the [color=#bf9000][b]yellow triangle[/b][/color] onto the empty triangle. [br][br]Before starting, feel free to adjust any aspect of the [color=#bf9000][b]starting triangle[/b][/color] ([color=#666666][b]tilt[/b][/color], [color=#1e84cc][b]size of the included angle[/b][/color], [b]and the positions of points [/b][i]A[/i][b], [/b][i]B[/i][b], and [/b][i]C[/i]). You can also use the [b]black slider[/b] to [b]change the position of the image (empty) triangle.[/b][i]Once you do start, it is recommended that you don't readjust these parameters. [/i]
