Which term refers to a closed figure formed by three or more line segments (called sides) that are connected end to end in a two-dimensional plane?

• Circle
• Oval
• Polygon
• Sphere

You are asked to draw a regular hexagon. Which of the following must be true about the angles and sides of your drawing?

• All angles and all sides are equal
• All sides are equal, but angles may differ
• It has five equal angles and five equal sides
• All angles are 90°, and opposite sides are equal

You’re designing a garden and want it to have five straight sides. Which of the following shapes would best fit your design?

• Decagon
• Pentagon
• Rectangle
• Triangle

Which type of angle is created when one side of a polygon is extended and forms an angle with its adjacent side?

• Acute Angle
• Exterior Angle
• Interior Angle
• Obtuse Angle

Which of the following statements below is TRUE about Dodecagon

I. Has 12 sides

II. Has 12 triangles formed by drawing diagonals from one vertex

III. The sum of its interior angles is 1800°

IV. The sum of its exterior angles is 180°

• I only
• II only
• I and III
• II and IV

Which of the following pairs of angles is complementary?

• 90° and 90°
• 85° and 95°
• 70° and 110°
• 60° and 30°

Two angles, ∠A and ∠B, are supplementary. If ∠A measures 3 times as much as ∠B, which of the following statements correctly describes the relationship between their measures?

• ∠A = 120°, ∠B = 60°, because 3(60) = 180.
• ∠A = 135°, ∠B = 45°, because 3(45) = 135 and their sum is 180°.
• ∠A = 150°, ∠B = 30°, because 150° is always supplementary to 30°.
• ∠A = 90°, ∠B = 90°, because supplementary angles are always equal.

Which of the following best describes the relationship between a pair of vertical angles?

• They are adjacent angles that add up to 180°.
• They are angles on a straight line that form a linear pair.
• They are non-adjacent angles that are always equal in measure.
• They are angles that add up to 90° and are formed by perpendicular lines.

Which of the following is a concave/non-convex polygon?

• 
• 
• 
• 

What makes a polygon regular and convex?

• The polygon has 8 sides and includes curved edges
• All sides are equal, and at least one angle points inward
• All sides and angles are equal, and all angles point outward
• All sides are different, and at least one angle is greater than 180°
