eight
Start with one octagon.Place an octagon along every other side of the first octagon. This creates square gaps which can be filled using the squares. At this stage the general pattern should be evident.
Using a protractor an 8 sided octagon angles will add up to 1080 degrees Or use the formula: (n-2)*180 = sum of interior angles whereas 'n' is the number of sides of the polygon
You draw a line segment from the corner to the opposing side's central point, then repeat with other two corners.
If you mean the area of a regular octagon with 8 equal sides of 3 cm then by using trigonometry its area works out as 43.36 square cm rounded to two decimal places.
A beaker is used to measure volume using water displacement.
An 8 sided octagon has 8 interior angles that add up to 1080 degrees which can be proven by using a protractor
I like using the word octagon in a sentence.
An octagon is a shape with eight sides.
We know that an octagon is an eight-side polygon. Since each side has the same distance form the center of the circumscribed circle of the octagon, this octagon is a regular octagon. If we draw the radii of the circle (their endpoints there are at the vertexes of the octagon), we form 8 isosceles triangle, which radius represents two their congruent sides with a measure of 7.5 cm, and the distance drawn from the center of the circle to the sides of the octagon represents their altitudes with a measure of 6.9 cm. So, by using the Pythagorean theorem we can find the half of the side of the octagon, which is: 7.5)^2 - (6.9)^2 = 8.64 Since one half of the octagon side is square root of 8.64, the whole side is 2(square root of 8.64) Thus the perimeter of this octagon is approximately 47 cm [8 x 2(square root of 8.64)].

making an octagon using diamond shapes
Using the formula: 0.5*(64-24) = 20 diagonals
Using a mirror or any form of TIR yes you can, but unfortunately the human eye cannot see around corners.
There are 48 triangles that can be formed because 6 triangles can be formed usin each point multiplied by 8.

You cannot measure an angle using a ruler.
