The folds create four geometric kites. Also, the 16 right triangles adjacent to the corners of
the paper are all congruent, as are the 8 right triangles adjacent to the center of the paper.
Find the measures of all four angles of the kite labeled ABCD. Use the facts that ZB « ZD
and that the interior angle sum of a quadrilateral is 360°
