How do you find the area of Apolygon?
To find the area of a regular polygon, all you have to do is follow this simple formula: area = 1/2 x perimeter x apothem.
What is regular Pentagon?
In the pentagon, the sum of the interior angles is equal to 540°. If all the sides are equal and all the angles are of equal measure, then it is a regular pentagon. Otherwise, it is irregular. In the regular pentagon, each interior angle measures 108°, and each exterior angle measures 72°.
What is apothem of hexagon?
The apothem of a hexagon is the length of the line that joins the center of the hexagon with the center of one side. The apothem is the perpendicular line that connects the center of the hexagon with one side.
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.
How do you find the area of a 4 sided shape?
Use the following equation:
- Area = side × side or A = s.
- Example: If one side of a square has a length of 4 feet, (t = 4), then the area of this square is simply t2, or 4 x 4 = 16 square feet.
What is the area of 2D shapes?
Area of 2D Shapes Formula
| Shape | Area | Terms |
|---|---|---|
| Square | a2 | a = length of side |
| Rectangle | l × w | l = length w = width |
| Parallelogram | b × h | b=base h=vertical height |
| Trapezium | ½(a+b) × h | a and b are the length of parallel sides h = height |
What is the apothem of a octagon?
The apothem is a straight line from the centre of the pentagon to the side, intersecting the side at a 90º right angle. For octagon, apothem is its height.
Is the apothem the radius?
The apothem of a regular polygon is the line segment drawn from the center of the polygon perpendicular to one of its edges. It is also the radius of the inscribed circle of the polygon.
What is a shape called with 6 sides?
hexagon
In geometry, a hexagon can be defined as a closed two-dimensional polygon with six sides. Hexagon has 6 vertices and 6 angles also.
