Beginning Angles Review

The angle relationship shown are -

• complementary angles

• supplementary angles

• vertical angles

• angle bisector

<COB and <AOD are vertical angles. The m<COB is 5x°. The m<AOD is 115°. Solve for x

• x = 13°

• x = 23°

• x = -5°

• x = 5°

What are complementary 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 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
