POLIGONOS

What defines a polygon?

• A geometric figure that is flat and closed, formed by 3 or more straight segments.

• A geometric figure that is flat and open, formed by 3 or more straight segments.

• A geometric figure that is flat and closed, formed by curved lines.

• A geometric figure that is three-dimensional and closed, formed by 3 or more straight segments.

What is a characteristic of a concave polygon?

• All its angles are less than 180 degrees.

• At least one of its angles is greater than 180 degrees.

• All its sides have the same length.

• It has exactly three sides.

What is the difference between regular and irregular polygons?

• Regular polygons have all sides of different lengths, while irregular polygons have all sides of the same length.

• Regular polygons have all sides of the same length, while irregular polygons have at least one side with a different length.

• Regular polygons have all angles less than 90 degrees, while irregular polygons have at least one angle greater than 90 degrees.

• Regular polygons are always convex, while irregular polygons are always concave.

How are triangles classified based on their angles?

• Acute-angled (all angles < 90°), right-angled (one angle = 90°), obtuse-angled (one angle > 90°).

• Equilateral (all sides equal), isosceles (two sides equal), scalene (all sides different).

• Convex (all angles < 180°), concave (one angle > 180°).

• Regular (all sides equal), irregular (sides not equal).
