Triangle Similarity
Combination 1
In Plane 1, you will see two triangles, ABC and DEF, and sliders labelled AB, ABC, BAC, and s.
Directions
Move the sliders to any value you want. This will transform the triangles in the plane. You may drag the triangles and labels around to arrange them and avoid overlap and scroll your mouse to zoom in and out. It would help to have segments AB and DE be in the same orientation.
