What is a regular polygon?

Back

A regular polygon is a polygon that is both equilateral (all sides are of equal length) and equiangular (all angles are of equal measure).

Front

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

Back

The sum of the exterior angle measures of any polygon, one at each vertex, is always 360 degrees.

Front

What is a concave polygon?

Back

A concave polygon is a polygon that has at least one interior angle greater than 180 degrees, causing at least one vertex to point inward.

Front

What is a convex polygon?

Back

A convex polygon is a polygon where all interior angles are less than 180 degrees, and no vertices point inward.

Front

How do you determine if a shape is a polygon?

Back

A shape is a polygon if it is a closed figure formed by three or more straight line segments that do not intersect except at their endpoints.

Front

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

Back

The sum of the interior angles of a polygon can be calculated using the formula (n - 2) × 180 degrees, where n is the number of sides.

Front

What is an equilateral triangle?

Back

An equilateral triangle is a triangle in which all three sides are of equal length and all three angles are equal, each measuring 60 degrees.

Front

What is an equiangular triangle?

Back

An equiangular triangle is a triangle in which all three angles are equal, each measuring 60 degrees, and thus it is also equilateral.

Front

What is the difference between a regular and irregular polygon?

Back

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

Front

What is a vertex in a polygon?

Back

A vertex is a point where two sides of a polygon meet.
