Thank You so much the link was helpful and I found my answer :-)
You're very welcome. :-)
When a third line intersects two parallel lines, several angle relationships are formed. To understand these relationships, you can follow these steps:
Step 1: Identify the parallel lines. Look for two lines in the given diagram that are parallel to each other. These lines will never intersect or meet.
Step 2: Locate the transversal. Identify the third line that intersects the two parallel lines. This line is known as a transversal.
Step 3: Identify corresponding angles. Corresponding angles are formed when a transversal intersects two parallel lines. They are in the same position relative to the transversal but on different lines. Corresponding angles are congruent or equal.
Step 4: Identify alternate interior angles. Alternate interior angles are formed when a transversal intersects two parallel lines. They are located on opposite sides of the transversal and in between the parallel lines. Alternate interior angles are congruent or equal.
Step 5: Identify alternate exterior angles. Alternate exterior angles are formed when a transversal intersects two parallel lines. They are located on opposite sides of the transversal and outside the parallel lines. Alternate exterior angles are congruent or equal.
Step 6: Identify consecutive interior angles. Consecutive interior angles are formed when a transversal intersects two parallel lines. They are located on the same side of the transversal and on the inside of the parallel lines. Consecutive interior angles are supplementary, which means they add up to 180 degrees.
By following these steps, you can easily identify and understand the angle relationships that form when a third line intersects two parallel lines.
