I need to write an indirect proof for this problem:
\n" ); document.write( "Given- AB is not equal to DE & AC is congruent to CD
\n" ); document.write( "Prove measure of angle B is not equal to measure of angle E
\n" ); document.write( "there is a picture of two triangles facing each other and sharing one point- the tops of each triangle and the letters read from left to right- top left point A, middle point where both triangles meet point C, then next top point is point D, lower right point E, then C again, lower left point is point B.
