A seven-sided shape is called a heptagon. A heptagon is one type of polygon, which can have any number of sides.
Continue ReadingA 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.

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 >To calculate the area in square yards of a square or rectangular shape, multiply the length by the width. If the dimensions of the shape are not given in yards, it is necessary to convert it first. An explanation for converting one unit to another is available from MathIsFun.com.
Full Answer >In geometry, the term congruent refers to two items being the same size and shape. Congruent can be used to describe shapes, sides, segments and/or angles.
