What are vertical angles?

• Angles that are adjacent to each other
• Angles that add up to 180°
• Angles that are opposite of each other when lines intersect
• Angles that add up to 90°

What are supplementary angles?

• Angles that add up to 180°
• Angles that add up to 90°
• Angles that are equal to each other
