[size=200][b][color=#ff0000]A line that crosses two lines is called a TRANSVERSAL. [/color][/b][/size]

[size=150][b][color=#0000ff]If we draw two parallel lines and then draw a line transversal through them, we will get eight different angles. [/color][/b][/size]

[size=200][b][color=#ff0000]Interior/Exterior Angles in a Transversal. [/color][/b][/size]

[size=150][b][color=#1155cc]The angles [i]between [/i]the parallel lines are called the interior angles. [/color][/b][/size]

[b][color=#1155cc][size=150]The angles that are on the outside of the parallel lines are called exterior angles. [/size][/color][/b]

[size=200][b][color=#ff0000]Alternate/Corresponding Angles in a Transversal[/color][/b][/size]

[b][color=#85200c][size=150]Corresponding angles are matching angles on the same side of the transversal. Study the image below to see all corresponding angles in a transversal. [/size][/color][/b]

[size=150][b][color=#0000ff]Alternate angles are matching angles that are across from each other on the transversal. [/color][/b][/size]

[b][color=#a61c00][size=150]Use the Interactive and the chart below to learn the locations of interior, exterior, corresponding and alternate angles in a transversal. [/size][/color][/b]
