Front

What is a polygon?

Back

A polygon is a closed figure formed by a finite number of straight line segments connected end to end.

Front

What defines a regular polygon?

Back

A regular polygon is a polygon with all sides and all angles equal.

Front

What is an irregular polygon?

Back

An irregular polygon is a polygon that does not have all sides and angles equal.

Front

How do you classify polygons based on the number of sides?

Back

Polygons can be classified as triangles (3 sides), quadrilaterals (4 sides), pentagons (5 sides), hexagons (6 sides), etc.

Front

What is congruence in geometry?

Back

Congruence in geometry means that two figures have the same shape and size.

Front

What are corresponding sides in polygons?

Back

Corresponding sides are sides in two polygons that are in the same relative position.

Front

What is the sum of the interior angles of a polygon with n sides?

Back

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

Front

What is the difference between convex and concave polygons?

Back

A convex polygon has all interior angles less than 180 degrees, while a concave polygon has at least one interior angle greater than 180 degrees.

Front

How can you determine if two polygons are congruent?

Back

Two polygons are congruent if their corresponding sides and angles are equal.

Front

What is a diagonal in a polygon?

Back

A diagonal is a line segment that connects two non-adjacent vertices in a polygon.
