All eight sides of an octagon are equal in length, and all eight angles are equal in size. This uniformity creates a direct relationship between the length of a side and the octagon area. Therefore, if you already know the area, you can derive the side length using the following formula,...
The easiest shape for which to calculate volume is a rectangular container, such as a fish tank or a show box. It has three sides of lengths a, b and c. You probably already know that you can calculate the area of a cross section of the box by multiplying its ...
So, our new formula for finding the measure of an angle in a regular polygon is consistent with the rules for angles of triangles that we have known from past lessons. Example 2 To find the measure of an interior angle of a regular octagon, which has 8 sides, apply the formula above...
The angles in an octagon (an 8-sided polygon) total 1080 degrees. 3 Divide the total measure of all of a regular polygon's angles by the number of its angles. A regular polygon is a polygon whose sides are all the same length and whose angles all have the same measure. For instance...
Most commonly associated with the shape of a "Stop" sign, the octagon has eight sides that are equal in length. The circumference of an octagon, also known as the perimeter, can be calculated by using a simple mathematical formula and a length measuring device such as a tape measure. ...
The calculation for the radius of a square relies on the Pythagorean Theorem that describes the relationships of the sides of a right triangle: a2+b2=c2 The radius of the square is c, the hypotenuse of a right triangle with sides, a and b, that are half the lengt...
