A seven-sided shape is called a heptagon. A heptagon is one type of polygon, which can have any number of sides.Know More
A polygon is defined as a two-dimensional or plane figure that consists of line segments, which are called edges or sides. The points at which the segments meet are called vertices or corners. Additionally, only two sides meet at each corner of a polygon.
There are five types of polygons:
A seven-sided polygon is called a heptagon. Polygon names are derived from the Greek language and are formed by using a prefix based on the Greek and adding it to the suffix "gon."
Polygons can have nearly an infinite number of sides, where the letter n represents the number of sides and the word is written "n-gon." For example, a polygon with 47 sides would be written as 47-gon. Another naming convention for polygons with more than 20 sides involves using the Greek prefix for the tens digit, plus "kai," which is the Greek for "and," plus the single digit, and finally the suffix "gon," which would make a 47-sided polygon a tetracontakaiheptagon.Learn more about Geometry
In real life, there are many different applications of geometry including everyday uses such as the "stop sign," which is an octagon shape. The shape, volume, location, surface area and various other physical properties are central to the objects around people.Full Answer >
A rectangle is a simple shape that is characterized by having four sides at 90-degree angles to each other, and having both sets of opposing sides be the same length. Note that if all sides are equal to each other, the shape is not a rectangle, but a square.Full Answer >
If a shape or image can be rotated less than 360 degrees and still retain the same appearance, this shape has rotational symmetry. For example, a five-pointed star can be turned to allow a different point to face upward and still appear as a five-pointed star; that's because this shape has rotational symmetry.Full Answer >
A quadrilateral is a four-sided shape, such as a rectangle or parallelogram. In order for a shape to be considered a quadrilateral, it has to have four straight sides and be two-dimensional.Full Answer >
