How many diagonal lines of symmetry are there in an octagon?
Assuming thatdiangle = diagonalsemetry = symmetryoctigon = octagonthe answer is 0, 1, 2, 4 or 8.
How many parallel lines does an octagon?
An octagon had four pairs of parallel lines.
How many diagonal lines does an octagon have?
A diagonal line of a polygon is a line that joins any two vertices not already joined by a side. A polygon with n sides has n(n-3)/2 diagonals → an octagon has 8(8-3)/2 = 8 × 5 ÷ 2 = 20 diagonals
How many lines of reflective symmetry does an octagon have?
An octagon has 8 lines of reflective symmetry.
The sum of the interior angle measures of an octagon?
To find interior angle measurements, you must divide the shape into triangles by drawing diagonal lines. The diagonal lines draw triangles, and the interior angle measure of triangles are always 180 degrees. The sum of interior angles of an octagon is 1080 degrees. How ever many triangles you have, multiply it by 180. See octagons in the link for more help,
