Unit 5: Polygon Angles

Front

What is the formula to calculate the sum of the interior angles of a polygon?

Back

The sum of the interior angles of a polygon with n sides is given by the formula: (n - 2) × 180 degrees.

Front

How many sides does a polygon have if the sum of its interior angles is 360 degrees?

Back

A polygon with a sum of interior angles of 360 degrees has 4 sides (a quadrilateral).

Front

Calculate the sum of the interior angle measures of a polygon with 25 sides.

Back

4140 degrees.

Front

What is the sum of the interior angles of a 24-gon?

Back

3960 degrees.

Front

If a polygon's interior angles add up to 2700 degrees, how many sides does it have?

Back

17 sides.

Front

What is the measure of each interior angle of a regular polygon with 8 sides?

Back

Each interior angle measures 135 degrees.

Front

What is the relationship between the number of sides and the sum of the interior angles of a polygon?

Back

As the number of sides increases, the sum of the interior angles increases according to the formula (n - 2) × 180 degrees.

Front

Find the value of x if the interior angles of a polygon are 50 degrees and 61 degrees.

Back

x = 50, y = 61.

Front

What is the measure of each exterior angle of a regular polygon with 10 sides?

Back

Each exterior angle measures 36 degrees.

Front

How do you find the number of sides of a polygon if you know the sum of its interior angles?

Back

Use the formula: n = (sum of interior angles / 180) + 2.
