Angle Relationships

Which angles are vertical angles?

What angle is vertical to angle 2?

• ∠4

• ∠1

• ∠2

• ∠5

What type of angles are these?

• Adjacent Angles

• Linear Pair

• Complementary Angles

• Supplementary Angles

• Vertical Angles

Tell whether the angles are complementary or supplementary. Then find the value of x.

• Complementary; x=25
• Complementary; x=5
• Supplementary; x=25
• Supplementary; x=5

• 15
• 16
• 18
• 19

• 2x-6=7x+4
• 2x-6+7x+4=90
• 2x-6+7x+4=180
• 2x-6+7x+4=360

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

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