 A', ZB = Z B', ZC = Z C". The first two statements cannot be true, for the sum of the angles of the two triangles would exceed four right angles. Therefore, two angles of one triangle are equal to two angles of the other.  Mathematics - Page 193by United States. Bureau of Naval Personnel - 1951Full view - About this book
