Math 8: Weekly Review #15

What are supplementary angles?

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

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°

Which are pairs of vertical angles?

• ∠COB & ∠COA
• ∠AOD & ∠AOC
• ∠COB & ∠AOD
• ∠BOD & ∠AOD

If ∠COB is 124°, then what is ∠BOD? How are they related?

• 56°, they are supplementary
• 90°, they are complementary
• 124°, they are vertical

Vertical angles are always

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