Polygon Angles and Parallelogram Properties

Front

What is the sum of the measures of the exterior angles of any polygon?

Back

360 degrees.

Front

How do you calculate the sum of the interior angles of a polygon with n sides?

Back

The sum is given by the formula: (n - 2) * 180 degrees.

Front

If the sum of the interior angles of a polygon is 2880 degrees, how many sides does it have?

Back

18 sides.

Front

What is the measure of one exterior angle of a regular polygon with 8 sides?

Back

45 degrees.

Front

How do you find the number of sides of a regular polygon if you know the measure of one interior angle?

Back

Use the formula: n = 360 / (180 - interior angle).

Front

What is the relationship between the interior and exterior angles of a polygon?

Back

Interior angle + Exterior angle = 180 degrees.

Front

In a parallelogram, what can you say about the opposite angles?

Back

Opposite angles are equal.

Front

What is the property of the diagonals in a parallelogram?

Back

The diagonals bisect each other.

Front

If ABCD is a parallelogram, what can you say about the lengths of opposite sides?

Back

Opposite sides are equal in length.

Front

What is the formula for the area of a parallelogram?
