What is a polygon?

Back

A polygon is a closed figure formed by a finite number of straight line segments that connect to form a shape.

Front

How do you calculate the sum of the interior angles of a polygon?

Back

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

Front

What is the sum of the interior angles of a triangle?

Back

The sum of the interior angles of a triangle is 180°.

Front

What is the sum of the interior angles of a quadrilateral?

Back

The sum of the interior angles of a quadrilateral is 360°.

Front

If a polygon has 5 sides, what is the sum of its interior angles?

Back

The sum of the interior angles of a pentagon (5 sides) is 540°.

Front

What is a convex polygon?

Back

A convex polygon is a polygon where all interior angles are less than 180° and no line segment between two points on the boundary ever goes outside the polygon.

Front

What is a concave polygon?

Back

A concave polygon is a polygon that has at least one interior angle greater than 180°, causing a 'cave' or indentation in the shape.

Front

How many sides does a decagon have?

Back

A decagon has 10 sides.

Front

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

Back

Each interior angle of a regular hexagon is 120°.

Front

If the sum of the interior angles of a polygon is 1080°, how many sides does it have?

Back

The polygon has 8 sides (octagon).
