There are a few simple shapes with equal sides. The basic shapes are a square, octagon, and an equilateral triangle,
from there sides
Shapes having less than 4 sides or more than 4 sides are not parallelograms
There is no special name: they are polygons, as are shapes with 3 or 3 million sides.
All regular polygons with an even number of sides. Irregular polygons with an odd number of sides can have parallel sides. There are also non polygonal shapes that can have parallel sides.
No
None because no triangle has any parallel sides.
In a regular nonagon no two sides are parallel.
a square
You mean lines or sides? But,octagon has parallel lines. Um, four parallel lines.
If you meant a shape then it could be a square or a rhombus
It can only be none other than a trapezoid.
Take your pick from a square, a rhombus, a rectangle or a parallelogram
There is no comprehensive list. In fact, there cannot be one. For example, polygons are named after the number of their sides and they can have infinitely many sides.
No. Sides cannot equal 360 degrees since they are not measured in degrees. The sum of the [interior] angles depends on the number of sides.
They are the boundaries of the shapes.
Shapes that have four sides are known as quadrilaterals.
