area
the perimeter. the space inside is the area
It is its square area
A perpendicular segment drawn from a vertex to the line that contains the opposite side
A polygon region is the area inside the boundaries of a polygon.
The amount of space inside a polygon is called its area. Area is measured in square units and can be calculated using different formulas depending on the type of polygon. For example, the area of a rectangle is found by multiplying its length by its width, while the area of a triangle can be calculated using the formula ( \frac{1}{2} \times \text{base} \times \text{height} ).
No it is not. A polygon is a plane space enclosed by straight lines. A letter "E" does not enclose any space and so cannot be a polygon.
Then the point is not outside the polygon...?
It is the interior of the polygon.
are you asking for the angle measure of an angle inside a polygon? Not sure what you want to know.
the circle is inscribed in the polygon
It is concave.
