In this video post we write about making of the model maths working model – maths tlm – parallel lines cut by a transversal model exhibition

Parallel lines are lines in the same plane that never intersect, no matter how far they are extended. When a line (called a transversal) intersects two or more parallel lines, it creates a series of angles. These angles have special properties, as described below:

Alternate interior angles: Alternate interior angles are pairs of angles that are located on opposite sides of the transversal and between the parallel lines. If the parallel lines are cut by the transversal, the alternate interior angles are congruent (equal in measure).

Alternate exterior angles: Alternate exterior angles are pairs of angles that are located on opposite sides of the transversal and outside the parallel lines. If the parallel lines are cut by the transversal, the alternate exterior angles are congruent (equal in measure).

Corresponding angles: Corresponding angles are pairs of angles that are located on the same side of the transversal and have the same relative position with respect to the parallel lines. If the parallel lines are cut by the transversal, the corresponding angles are congruent (equal in measure).

Same-side interior angles: Same-side interior angles are pairs of angles that are located on the same side of the transversal and between the parallel lines. If the parallel lines are cut by the transversal, the same-side interior angles are supplementary (add up to 180 degrees).
