document.write( "Best answer d).  In fact the two triangles <i>could</i> be congruent, but you can't prove it.  And you can't actually prove that they are not congruent either (unless the difference in size as they are drawn is clearly and measurably different).  They are, in fact similar.  But you are only told that EF = 4, and you have no idea of the measure of the corresponding side of RST.  All you can do, because you know that the three angles must all be equal in measure to their corresponding angles, R and F, S and E, T and D, is say that the two triangles are <i>similar</i>\r<BR>\n" );
