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.
Two angles are said to be supplementary when the sum of the two angles is 180Â°. If we have two parallel lines and have a third line that crosses them as in the ficture below - the crossing line is called a transversal. When a transversal intersects with two parallel lines eight angles are produced. The eight angles will together form four pairs of corresponding angles. Angles 1 and 5 constitutes one of the pairs. Corresponding angles are congruent. All angles that have the same position with regards to the parallel lines and the transversal are corresponding pairs e.g. 3 + 7, 4 + 8 and 2 + 6. Angles that are in the area between the parallel lines like angle 2 and 8 above are called interior angles whereas the angles that are on the outside of the two parallel lines like 1 and 6 are called exterior angles. Angles that are on the opposite sides of the transversal are called alternate angles e.g. 1 + 8. All angles that are either exterior angles, interior angles, alternate angles or corresponding angles are all congruent. Example. The picture above shows two parallel lines with a transversal.
