Presentation Transcript


Identify parallel perpendicular and skew lines

Objectives

Identify parallel, perpendicular, and skew lines.

Identify the angles formed by two lines and a transversal.


Identify parallel perpendicular and skew lines

Vocabulary

parallel lines

perpendicular lines

skew lines

parallel planes

transversal

corresponding angles

alternate interior angles

alternate exterior angles

same-side interior angles


Identify parallel perpendicular and skew lines

Helpful Hint

Segments or rays are parallel, perpendicular, or skew if the lines that contain them are parallel, perpendicular, or skew.
