Types of Angles

• Corresponding Angles

• Alternate Interior Angles

• Alternate Exterior Angles

• Supplementary Angles

• Same-side Interior Angles

• Same-side Exterior Angles

• Linear Pair

Parallel, Perpendicular, & Skew Lines

• Parallel lines - never touch, must be in the same plane

• Perpendicular lines - intersect at 90 degrees, form a 'corner'

• Skew Lines -- Not parallel, not intersecting, on different planes
