A regular octagon has 8 sides.
Only if all the SIDES are EQUAL in length. Equi -> Equal Lateral -> Sides To actually answer the question: An octagon has all sides the same length and its internal angles are all the same size. All regular polygons except for a triangles are equilateral.
A regular octagon has 8 lines of symmetry.
Yes.

If you cut a regular octagon into triangles, it would be 6 triangles. the measurement of all the angles in a triangle added up are 180 degress multiply 6x180=1080 the measurement of all the angles in a octagon added up are 1080 degress there are 8 angles in a octagon. divide 1080 by 8=135 135 degress in each angle in a regular octagon
No, there would be triangles in between. Sorry!
It has 20 diagonals and is made up by 6 triangles
In general, an octagonal pyramid is a pyramid with an octagon for a base and triangles (which all have a common vertex) for sides. The octagon my or may not be a regular one.
