Angle Definitions and Relationships

• Alternate Interior Angles

• Alternate Exterior Angles

• Same-side Interior Angles

• Corresponding Angles

• None of these

Vertical angles are always

• acute
• total 180 degrees
• congruent (equal measures)
• adjacent angles

Supplementary angles always add up to
