Polygon refers to two dimensional shapes that is created by straight line segments connected to form polygonal circuits. When rotated they have the same lengths and angle measures because it is equilateral and equiangular and rotated at 360 degrees.
This means that it has equal side lengths and equal measure angles.
The number of lines of reflection symmetry is the same as the side of polygon because it has the same length.
For example, Pentagon is a five sided polygon, when rotated, it has five lines order of symmetry. The angle of rotation is 360 degrees, therefore 369 degree is divided by the five lines of symmetry which is 72 degrees.
Coal is called a fossil fuel because it was made from plants that were once alive! Since coal comes from plants, and plants get their energy from the sun, the energy in coal also came from the sun.
