The measure of the interior of a closed figure refers to the area contained within its boundaries. This area can be calculated using various mathematical formulas depending on the shape of the figure, such as triangles, rectangles, or circles. In geometry, the interior is often contrasted with the exterior, which is the space outside the closed figure. Understanding the interior measure is essential in fields such as architecture, engineering, and various design applications.
The interior angles measure 360 degrees.
A polygon is a closed plane figure bounded by straight sides. Since it is a closed surface, it has an interior (inside) and an exterior (outside). The interior angle of a polygon is the angle formed by two adjacent sides such that the angle is facing the interior of the polygon.
The angles have the same measure. In the reflection the order of the angles are changed from clockwise to counterclockwise.
A closed plane figure with all sides and angles congruent is known as a regular polygon. Examples include regular triangles (equilateral triangles) and regular quadrilaterals (squares). In a regular polygon, each side is of equal length, and each interior angle has the same measure. This symmetry gives regular polygons their distinctive geometric properties.

The interior angles measure 360 degrees.
A convex polygon with four sides is called a quadrilateral, and the sum of its interior angles is 360°. This is determined using the formula (n − 2) × 180°, where n represents the number of sides. Substituting 4 for n gives (4 − 2) × 180° = 360°. Whether it is a square, rectangle, parallelogram, rhombus, or trapezoid, every convex quadrilateral has interior angles that add up to 360°.

A closed plane figure with all sides and angles congruent is known as a regular polygon. Examples include regular triangles (equilateral triangles) and regular quadrilaterals (squares). In a regular polygon, each side is of equal length, and each interior angle has the same measure. This symmetry gives regular polygons their distinctive geometric properties.
