Holiday celebrations may be passed down as traditions, as is the case with this distinctly Polish Christmas meal and decor. A tradition is a belief or behavior passed down within a group or society with symbolic meaning or special significance with origins in the past.
Transversal (geometry) In geometry, a transversal is a line that passes through two lines in the same plane at two distinct points. Transversals play a role in establishing whether two other lines in the Euclidean plane are parallel. The intersections of a transversal with two lines create various types of pairs of angles: consecutive interior angles, corresponding angles, and alternate angles.
Each of the parallel lines cut by the transversal has 4 angles surrounding the intersection. These are matched in measure and position with a counterpart at the other parallel line. At each of the parallel lines, there are two pairs of vertical angle. Each angle in the pair is congruent to the other angle in the pair.
