What is a circle?

• A polygon with three sides.

• A round shape with all points equidistant from the center.

What is the difference between regular and irregular polygons?

• Regular polygons have all sides and angles equal, while irregular polygons do not.

• Regular polygons can have varying side lengths, while irregular polygons cannot.

• Irregular polygons have all sides equal, while regular polygons do not.

• Regular polygons are always triangles, while irregular polygons can be any shape.

What is the formula for the area of a circle?

• A = 2πr

• A = πr²

• A = πd

What is the relationship between the number of sides and the sum of interior angles in a polygon?

• The sum of the interior angles is equal to the number of sides multiplied by 180°.

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

• The sum of the interior angles is always 360° regardless of the number of sides.

• The sum of the interior angles is equal to the number of sides minus 2, multiplied by 90°.
