Polygons are shapes with two or more sides. They are made from lines that are joined together at certain angles. For a regular polygon, there are at least two sides that fuse to form a vertex. Some polygons have equal, interior angles while others do not. Also, exterior angles can be equal or not. Do you know so much about property of polygons?

• 1.

### What is a polygon with five sides called?

• A.

Hexagon

• B.

Pentagon

• C.

Decagon

• D.

Heptagon

B. Pentagon
Explanation
A polygon with five sides is called a pentagon.

### Which of these is not a type of polygon?

• A.

Simple polygon

• B.

Complex polygon

• C.

Concave polygon

• D.

Convex polygon

B. Complex polygon
Explanation
A complex polygon is not a type of polygon because a polygon is defined as a closed figure with straight sides. A complex polygon has intersecting sides, which violates the definition of a polygon. Simple polygon, concave polygon, and convex polygon are all valid types of polygons.

### What type of polygon do not intersect themselves?

• A.

Simple polygon

• B.

Complex polygon

• C.

Concave polygon

• D.

Convex polygon

A. Simple polygon
Explanation
A simple polygon is a type of polygon that does not intersect itself. It is a closed figure made up of straight line segments where no two segments intersect except at their endpoints. In other words, a simple polygon does not have any self-intersections or overlapping sides. This distinguishes it from a complex polygon, concave polygon, or convex polygon, which may have self-intersections.

### What is the sum of interior angles in simple polygons?

• A.

180 degrees

• B.

120 degrees

• C.

90 degrees

• D.

100 degrees

A. 180 degrees
Explanation
The sum of interior angles in simple polygons is always 180 degrees. This is a well-known geometric property that applies to all polygons, regardless of the number of sides. Each interior angle in a polygon can be calculated using the formula (n-2) * 180, where n is the number of sides. Therefore, the correct answer is 180 degrees.

• 5.

### What are all convex polygons called?

• A.

Compound polygons

• B.

Convex polygons

• C.

Special polygons

• D.

Simple polygons

D. Simple polygons
Explanation
Convex polygons are called simple polygons because they are made up of straight sides and do not intersect themselves. Each interior angle of a simple polygon is less than 180 degrees, and all vertices of the polygon point outwards. This distinguishes them from compound polygons, which are made up of multiple simple polygons joined together, special polygons, which have specific properties or characteristics, and other types of polygons that may have intersecting sides or angles greater than 180 degrees.

### What are polygons with equal edges called?

• A.

Isogonal figures

• B.

Equilateral figures

• C.

Tangential figures

• D.

Cyclic figures

B. Equilateral figures
Explanation
Equilateral figures are polygons with equal edges. The term "equilateral" refers to all sides of the polygon being of the same length. Therefore, this is the correct answer to the question. Isogonal figures refer to polygons with equal angles, tangential figures refer to polygons that can be inscribed within a circle, and cyclic figures refer to polygons that can be circumscribed around a circle.

Rate this question:

• 7.

### What is a polygons that has all sides perpendicular to each other called?

• A.

Tangential polygons

• B.

Isotoxal polygon

• C.

Regular polygon

• D.

Rectilinear polygons

D. Rectilinear polygons
Explanation
Rectilinear polygons are polygons that have all sides perpendicular to each other. This means that the angles formed between the sides of the polygon are all right angles. Therefore, the correct answer for this question is rectilinear polygons.

Rate this question:

• 8.

### What is the sum of all angles forming a polygon?

• A.

90 degrees

• B.

360 degrees

• C.

180 degrees

• D.

270 degrees

B. 360 degrees
Explanation
The sum of all angles forming a polygon is 360 degrees. This is because the sum of the interior angles of any polygon with n sides is equal to (n-2) * 180 degrees. Since a polygon can have any number of sides, the sum of the angles can vary. However, when we consider all possible polygons, the maximum sum of the angles occurs when the polygon has an infinite number of sides, which is a circle. In a circle, the sum of the angles is 360 degrees.

Rate this question:

• 9.

### Which of these is not a variety of polygon?

• A.

Apeirogon

• B.

Skew polygon

• C.

Spherical polygon

• D.

Axial polygon

D. Axial polygon
Explanation
An axial polygon is not a variety of polygon because it does not meet the definition of a polygon. A polygon is a closed figure with straight sides, while an axial polygon has curved sides. Therefore, an axial polygon cannot be classified as a variety of polygon.

Rate this question:

• 10.

### What kind of polygons have algebraic properties?

• A.

Abstract polygon

• B.

Special polygon

• C.

Inscribed polygon

• D.

Tangential polygon

A. Abstract polygon
Explanation
Abstract polygons are a type of polygon that is defined by its geometric properties rather than specific numerical values. These polygons are often used in abstract mathematics and can be described using algebraic equations or properties. Therefore, abstract polygons have algebraic properties. Special polygons, inscribed polygons, and tangential polygons may also have algebraic properties, but this is not necessarily true for all polygons in these categories.
