the only thing i can think of is that the 2 isosceles triangles are joined at the base.
\n" ); document.write( "in that case they would form a square with the diagonal being the base of the 2 triangles formed.
\n" ); document.write( "abcd is the square going around clockwise from the top left corner.
\n" ); document.write( "dab is one isosceles triangle.
\n" ); document.write( "bcd is the other isosceles triangle.
\n" ); document.write( "the common base is bd.
\n" ); document.write( "the 2 equal legs of the first triangle are da and ab.
\n" ); document.write( "the 2 equal legs of the second triangle are bc and cd.
\n" ); document.write( "4a refers to da and ab and bc and cd and means the triangles are congruent with the common base making all 3 corresponding sides of each triangle equal.
\n" ); document.write( "b is the common base bd.
\n" ); document.write( "that's the only way i can figure what they mean when they say 4a and 1b. \n" ); document.write( "
