Learn how to find the area of a regular polygon. Learn to apply the concepts to find the area of a regular pentagon and see examples.
In order to find the number of diagonals of a hexagon the following methods can be used. Number of diagonals in a polygon = 1/2 × n × (n-3), where n = number of sides in the polygon. Here, n = 6. After substituting this value of n = 6 in the formula we get, Number of...
Let’s know what a diagonal is. A diagonal of a polygon can be defined as aline segmentjoining two vertices. From any given vertex, there are nodiagonalsto the vertex on either side of it, since that would lay on top of the side. Also, remember that there is obviously no diagonal fro...
The regular hexagon formula is used to calculate the area, perimeter, and diagonals of a regular hexagon. Let’s say, each side of a regular hexagon is named 's'. To find the area, perimeter, and diagonals of a regular hexagon we use the following regular hexagon formulas. ...
A convex polygon has interior angles less than 180 degrees. The vertices of a convex polygon are always pointed outside the center. Interior angles and exterior angles.Convex and concave polygon.
Diagonals are a line joining two non-adjacent vertices of a polygon, i.e., a diagonal joins two vertices of a polygon excluding the edges of the figure. The diagonal of a square is a line segment that connects any two non-adjacent vertices. A square has two diagonals equal in length an...
So, the unit of area of a rectangle is ‘square units’. Let’s understand how to find the area of a rectangle using unit squares.Example 1: Divide the rectangle ABCD into unit squares, as shown. The area of a rectangle ABCD is the total number of unit squares contained within it....
Example: In the quadrilateral \(ABCD\) shown below, both the diagonals \(AD\) and \(BC\) lie inside the quadrilateral. Hence, \(ABCD\) is a convex quadrilateral.Perimeter of a QuadrilateralThe total length around any two-dimensional shape is called its perimeter. To find the perimeter of...
A rectangle is a four-sided polygon that has its opposite sides equal in length. All the 4 angles are 90 degrees. A rectangle is a two-dimensional flat shape. Area and perimeter of rectangle at BYJU’S
