• square

• rectangle

• rhombus

• triangle

Which quadrilateral has only ONE pair of parallel sides?

• square

• rectangle

• trapezoid

• parallelogram

What is the sum of the exterior angle measures of any polygon?

• 180

• 180 (n-2)

• 360

How do you find the sum of all angles inside a polygon?

• 360

• 180(n-2)

What is a regular polygon?

• Polygon with all sides congruent

• Polygon with all angles congruent

• Polygon with all sides and angles congruent

• Polygon with no sides or angles congruent

What is the formula to find the measure of EACH interior angle of a regular polygon?

• S=(n-2)*180

• S/n

• N/S

• S= (n-2)*180/n

What does the letter 'S' stand for in the formula S=(n-2)*180
