The video tutorial explains the concept of a transversal, a line that intersects two or more lines in a plane at different points. It discusses the angles formed by a transversal, including interior and exterior angles, alternate interior and exterior angles, and corresponding angles. The tutorial also covers the properties of these angles when the intersected lines are parallel, such as equal corresponding angles and supplementary interior angles on the same side of the transversal. The video concludes with methods to determine if two lines are parallel based on these angle properties.

What is a transversal?

• A line that intersects two or more lines at different points

• A line that runs parallel to another line

• A line that intersects only one line

• A line that forms a right angle with another line

Which angles are formed on the inner side of two lines by a transversal?
