Transversals a line intersecting two or more given lines in a plane at different points is called a transversal to the given lines.

Transversal to two parallel lines:

Angles made by a transversal with two lines

Parallel Lines and a Transversal

A line intersecting a sirrcle in two points is called a "_____"

A line intersecting a circle in two points is called a _________.

If a Transversal intersects two lines in such a way that a pair of alternate interior angles are equal; then the two lines are parallel.

Fill in the blanks in each of the following to make the statement true: (i) If two parallel lines are intersected by a transversal, then each pair of corresponding angles are.... (ii) If two parallel lines are intersected by a transversal, then interior angles on the same side of the transversal are... (iii) Two lines perpendicular to the same line are.... to each other. (iv) Two lines parallel to the same line are .......... to each other. (v) If a transversal intersects a pair of lines in such away that a pair of alternate angles are equal, then the line are... (vi) If a transversal intersects a pair of lines in such away that the sum of interior angles on the same side of transversal is 180,then the line are .......

Show that the locus of a point, equidistant from two intersecting lines in the plane, is a pair of lines bisecting the angles formed by the given lines.

If a transversal intersects two parallel lines; then each of alternate interior angles are equAL.
