What is the sum of the measures of the interior angles of a 25-gon?

Find the value of x.

Which quadrilaterals always have diagonals that are perpendicular?

• Parallelogram

• Rectangle

• Rhombus

• Square

Use your knowledge of inscribed angles to find x.

• x = 3

• x = 12

• x = 9

• x = -8

Use your knowledge of parallelograms to choose the TWO true statements.

• All four sides are congruent.

Use your knowledge of parallelograms to choose the correct setups that would allow you to solve for x and y.

• Sides: 13x+15 = 19x-9

  Angles: 4y+7 = 10y-37

• Sides: 13x+15 + 19x-9 = 180

  Angles: 4y+7 + 10y-37 = 360

• Sides: 13x+15 + 19x-9 = 180

  Angles: 4y+7 = 10y-37

• Sides: 13x+15 = 19x-9

  Angles: 4y+7 + 10y-37 = 180

• 52

• 90

• 38

• 44

The radius of this circle is 12cm. What is the total area of the shaded regions?
