1/5 Questions

What is the sum of the angles of a hexagon (6 sided polygon)?
- 720
- 900
- 1080
- 1260

About This Quiz

Use the following formula to solve the following problems. Sum of the angles = (n - 2)180, where n = number of sides

2.

What is the sum of the angles of an octogon (8 sided polygon)?
- 900
- 1080
- 1260
- 1440
Correct Answer

A. 1080

Explanation

An octagon is a polygon with 8 sides. To find the sum of the angles of any polygon, we use the formula (n-2) * 180, where n is the number of sides. In this case, the sum of the angles of an octagon would be (8-2) * 180 = 6 * 180 = 1080.

3.

What is the sum of the angles of an 11 sided polygon?
- 1980
- 1800
- 1620
- 1440
Correct Answer

A. 1620

Explanation

The sum of the angles in any polygon can be found using the formula (n-2) * 180, where n is the number of sides. In this case, the polygon has 11 sides, so the sum of the angles would be (11-2) * 180 = 9 * 180 = 1620.

Rate this question:
4.

How many sides does a polygon have if the sum of its angles is 1440?
- 8
- 9
- 10
- 11
Correct Answer

A. 10

Explanation

A polygon with 10 sides is called a decagon. The sum of the interior angles of a decagon is given by the formula (n-2) * 180, where n is the number of sides. Plugging in n=10, we get (10-2) * 180 = 8 * 180 = 1440. Therefore, a polygon with 10 sides would have an angle sum of 1440 degrees.

Rate this question:
5.

How many sides does a polygon have if the sum of its angles is 540?
- 6
- 5
- 4
- 3
Correct Answer

A. 5

Explanation

A polygon with 5 sides is called a pentagon. The sum of the interior angles of a polygon can be found using the formula (n-2) * 180, where n represents the number of sides. In this case, we have (5-2) * 180 = 540, which means that the sum of the angles in a pentagon is indeed 540. Therefore, the correct answer is 5.
