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 can be calculated using the formula: (n - 2) * 180°, where n is the number of sides.

How many sides does a heptagon have?

Back

A heptagon has 7 sides.

Front

What is the total of a heptagon's interior angles?

Back

The total of a heptagon's interior angles is 900°.

Front

What is the value of b if 2b + 5 = 79?

Back

b = 37.

Front

How do you solve for t in the equation 3t - 2 = 40?

Back

To solve for t, add 2 to both sides to get 3t = 42, then divide by 3 to find t = 14.

Front

What is the value of x in the equation 5x + 10 = 160?

Back

To solve for x, subtract 10 from both sides to get 5x = 150, then divide by 5 to find x = 30.

Front

How do you solve for s in the equation 4s + 1 = 37?

Back

To solve for s, subtract 1 from both sides to get 4s = 36, then divide by 4 to find s = 9.

Front

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

Back

The sum of the interior angles increases as the number of sides increases, following the formula (n - 2) * 180°.

Front

What is the definition of a polygon?

Back

A polygon is a closed figure formed by a finite number of straight line segments that connect to form a closed chain or circuit.

Front

What is the difference between a regular and an irregular polygon?

Back

A regular polygon has all sides and angles equal, while an irregular polygon does not.
