The sum of any tetracontaoctagon's interior angles is degrees. Octacontagon lines of symmetry octagon Vertices are colored by their symmetry positions. What is a Polygon? The midpoint octagon of a reference octagon has its eight vertices at the midpoints of the sides of the reference octagon. The sum of any pentacontagon's interior angles is degrees. If squares are constructed all internally or all externally on the sides of the midpoint octagon, then the midpoints of the segments connecting the centers of opposite squares themselves form the vertices of a square.
A line of symmetry is an imaginary line that separates shapes in half so that each half is a mirror image of the other.
