• Supplementary
• Complementary
• Right
• Vertical

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

Write an equation for the figure shown. 

• 7x + 110 = 90
• 7x + 110 =180
• 7x = 90
• 7x = 180

Which equation should we use to solve for x?

• x + 8 + 2x = 90

• x + 8 + 2x = 180

• x + 8 + 2x = 360

• x + 8 = 2x

Whose equation matches the diagram?

• Elena's Equation: $35+w+41=180$  

• Diego's Equation:  $w+35=180$  

What is the formula for finding the area of a circle?

• 
• 

A DVD has a diameter of 15 millimeters. Which equation would help you determine the circumference?

• c = 15π
• c = 2π15
• c = π(15²)
• c = π(7.5²)

The circumference of the clock in Jason's room is 43.96 in.

^{What would you do to determine the diameter of the clock?}

• Divide the circumference by 𝜋.

• Divide the circumference by 𝜋 to determine the radius; then divide the radius by 2.

• Divide the circumference by 𝜋 to determine the radius; then multiply the radius by 2.

• Multiply the circumference by 𝜋 .

The radius of a circle is

• The measurement from the center of a circle to an edge of the circle.
• The measurement around the circle
• The measurement from and edge of the circle to another edge through the center
• A line perpendicular to the diameter of the circle
