1.
How many sides does a pentagon have?
Correct Answer
C. Five
Explanation
A pentagon is a polygon with five sides. Therefore, the correct answer is five.
2.
What is the name of a four sided polygon?
Correct Answer
D. Quadrilateral
Explanation
A quadrilateral is a polygon with four sides. It is the correct answer because it accurately describes the shape being asked for in the question. A triangle has three sides, an octagon has eight sides, and a pentagon has five sides, so they are not the correct names for a four sided polygon.
3.
What is the least number of sides a polygon can have?
Correct Answer
B. Three
Explanation
A polygon is a closed figure with straight sides. In order for a figure to be considered a polygon, it must have at least three sides. Therefore, the least number of sides a polygon can have is three.
4.
How many angles are there in a triangle?
Correct Answer
A. Three
Explanation
A triangle is a polygon with three sides, and each side of a triangle forms an angle with the adjacent side. Therefore, a triangle has three angles.
5.
A stop sign is what type of polygon?
Correct Answer
B. Octagon
Explanation
A stop sign is an octagon because it has eight sides. The shape of a stop sign is specifically designed to be easily recognizable and to convey a sense of urgency to drivers. The octagonal shape helps to distinguish a stop sign from other road signs and signals, making it clear that drivers must come to a complete stop at that intersection.
6.
Can a polygon have cruved sides?
Correct Answer
B. No
Explanation
A polygon is a closed figure with straight sides. By definition, it does not have curved sides. Therefore, the correct answer is "no."
7.
What makes a polygon a regular polygon?
Correct Answer
D. All angles and sides are the same
Explanation
A regular polygon is defined as having all angles and sides that are the same. This means that every angle in the polygon is congruent and every side has the same length. This property distinguishes a regular polygon from other polygons where the angles or sides may vary.
8.
Which of the following is NOT a polygon?
Correct Answer
C. Circle
Explanation
A circle is not a polygon because it does not have straight sides. A polygon is a closed figure made up of straight line segments. A square, pentagon, and triangle all have straight sides and are considered polygons. However, a circle is a curved shape with no straight sides, therefore it is not a polygon.
9.
What type of polygon is this?
Correct Answer
A. Quadrilateral
Explanation
The given shape is a quadrilateral because it has four sides. A quadrilateral is a polygon with four sides and four angles.
10.
Which of the following is not a regular polygon?
Correct Answer
C. Rectangle
Explanation
A regular polygon has all sides of equal length and all interior angles of equal measure. An equilateral triangle, square, and regular hexagon meet these criteria. However, a rectangle does not because, while all angles are equal (90 degrees), its opposite sides are of equal length, but adjacent sides can differ in length. Therefore, it is not a regular polygon.
