What is a polygon?

• A simple closed curve made of only line segments
• A shape with curved edges
• A three-dimensional figure
• A shape with no sides

How do we classify polygons?

• By their color
• By the number of sides or vertices
• By their area
• By their angles

What is a diagonal in a polygon?

• A line segment connecting two consecutive vertices
• A line segment connecting two non-consecutive vertices
• A line segment connecting the midpoints of sides
• A line segment that is always horizontal

Which of the following describes a convex polygon?

• All diagonals lie outside the polygon
• At least one diagonal lies outside the polygon
• No portions of their diagonals lie in the exterior
• All sides are equal

What is a regular polygon?

• A polygon with unequal sides
• A polygon that is both equiangular and equilateral
• A polygon with only right angles
• A polygon with no sides

What is the angle sum property of a triangle?

• The sum of the angles is 90°
• The sum of the angles is 180°
• The sum of the angles is 360°
• The sum of the angles is 270°

What is a rhombus?

• A quadrilateral with all sides equal
• A quadrilateral with only right angles
• A quadrilateral with unequal sides
• A quadrilateral with one pair of parallel sides

Which property do the diagonals of a rhombus have?

• They are equal in length
• They are perpendicular bisectors of one another
• They are parallel
• They are always horizontal

What is a rectangle?

• A quadrilateral with all sides equal
• A parallelogram with equal angles
• A shape with curved edges
• A triangle with right angles

What is true about the diagonals of a rectangle?

• They are always different lengths
• They are equal in length
• They are perpendicular to each other
• They are not bisectors
