What is the definition of a polygon?

A polygon is a two-dimensional closed geometric figure with straight sides. It is made up of line segments that form a closed shape, where each segment intersects exactly two others at its endpoints.

What is the formula for finding the sum of the interior angles of a polygon?

The formula for finding the sum of the interior angles of a polygon is (n-2) x 180 degrees, where n represents the number of sides or angles in the polygon.

How many sides does a hexagon have?

A hexagon has six sides.

How many vertices does a triangle have?

A triangle has three vertices.

Is it possible for a polygon to have both acute and obtuse angles?

No, it is not possible for a polygon to have both acute and obtuse angles. A polygon is a closed figure made up of line segments, and its interior angles must total to a specific value based on the number of sides it has. Since acute angles are less than 90 degrees and obtuse angles are greater than 90 degrees, a polygon can only have one type of angle across all its interior angles.

What is the measure of each interior angle of a regular pentagon?

The measure of each interior angle of a regular pentagon is 108 degrees.

How many diagonals does a polygon with 5 sides have?

A polygon with 5 sides has 5 diagonals.

Can a polygon have more than one pair of parallel sides?

Yes, a polygon can have more than one pair of parallel sides. For example, a trapezoid has one pair of parallel sides, while a parallelogram has two pairs of parallel sides. Similarly, a rhombus, rectangle, and square all have multiple pairs of parallel sides. So, it is possible for a polygon to have more than one pair of parallel sides.

What is the relationship between the number of sides and the number of diagonals in a polygon?

The relationship between the number of sides and the number of diagonals in a polygon can be determined using the formula \(d = \frac{n(n - 3)}{2}\), where \(\boldsymbol{d}\) is the number of diagonals and \(\boldsymbol{n}\) is the number of sides. This formula accounts for the fact that every vertex can potentially connect to every other vertex except those adjacent to it and those separated by only one vertex, resulting in fewer diagonals than the total number of possible connections.

How many degrees are in the exterior angle of a regular octagon?

The exterior angle of a regular octagon measures 45 degrees.
