How it works ?
ANY 2 figures are said to be SIMILAR FIGURES if and only if one can be mapped perfectly onto the other under a single transformation OR a composition of 2 or more transformations.
The applet below dynamically illustrates what it means, by definition, for any 2 triangles to be similar. Feel free to move any of the white vertices anywhere you’d like. You can also change the size of the green triangle by moving the green slider.
