What is a polygon N?
In Geometry, a polygon is a closed two-dimensional figure, which is made up of straight lines. Generally, from the name of the polygon, we can easily identify the number of sides of the shape. For example, a triangle is a polygon which has three sides.
What is the meaning of N sides?
noun. The northern part or side of something; the north; also in extended use.
What is the area of N-sided polygon?
Often the formula is written like this: Area=1/2(ap), where a denotes the length of an apothem, and p denotes the perimeter. When an n-sided polygon is split up into n triangles, its area is equal to the sum of the areas of the triangles.
Which is the north side?
By convention, the top side of a map is often north. To go north using a compass for navigation, set a bearing or azimuth of 0° or 360°. North is specifically the direction that, in Western culture, is considered the fundamental direction: North is used (explicitly or implicitly) to define all other directions.
What is a vertex of a polygon?
A point at which two polygon edges of a polygon meet.
What is an apothem in math?
Definition of apothem : the perpendicular from the center of a regular polygon to one of the sides.
What is apothem in polygon?
The apothem (sometimes abbreviated as apo) of a regular polygon is a line segment from the center to the midpoint of one of its sides. Equivalently, it is the line drawn from the center of the polygon that is perpendicular to one of its sides.
What is concave and convex polygon?
A convex polygon is a polygon where all the interior angles are less than 180º. A polygon in which at least one of the angles is greater than 180° is called a concave polygon.
What is a polygon trapezoid?
< Geometry Course | Polygon | Quadrilateral. A Trapezoid (American English) or Trapezium (British English) is a quadrilateral that has two parallel sides and two non parallel sides. Some properties of trapezoids: The interior angles sum to 360° as in any quadrilateral. The parallel sides are unequal.
What is diagonal polygon?
A diagonal of a polygon can be defined as a line segment joining two vertices. From any given vertex, there are no diagonals to the vertex on either side of it, since that would lay on top of the side.
What is apothem of pentagon?
Apothem is the line from the center of the pentagon to a side, intersecting the side at 90 degrees right angle.
What is Circumradius polygon?
The circumradius of a cyclic polygon is a radius of the circle inside which the polygon can be inscribed. Similarly, the circumradius of a polyhedron is the radius of a circumsphere touching each of the polyhedron’s vertices, if such a sphere exists.
Is apothem and radius the same thing?
The apothem of a regular polygon is a segment connecting the center of the polygon to a midpoint of one of the sides, and the radius of a regular polygon is a segment connecting the center of the polygon to one of the vertices.
