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.
Sometimes parallel lines are indicated by pointers on the lines. When two parallel lines are cut by a third line, called a transversal, the three lines form a system of congruent angles. In this figure, vertical angles 1 = 4 and 5 = 8. Because line a and line b are parallel, 1 = 5 and 4 = 8. So the four angles are congruent: 1 = 4 = 5 = 8.
