An octagon does not have 180 degrees.
Consider, - travelling anti clockwise around the Octagon, we first turn 45o to the SW, followed by another turn of 45o to the S. And so around the octagon till we have turned left eight times. A total of 360 degrees. (Almost by definition since we finish up where we started.) That is the sum of the external projected angles - the deflections from a straight line.
The internal angles are 135o , (180 - 45), so the sum of the internal angles is 8 x 135.
a triangle is 180 degrees a square is 2 triangles so it is 360 degrees an octagon is 8 sides 720 degrees 180 times 4 = 720 degrees
The sum of the interior angles of an octagon is (8-2)*180 = 1080 degrees.
No because each interior angle of a regular octagon measures 135 degrees But each interior and exterior angles add up to 180 degrees
The interior angles of any polygon add up to the number of sides - 2, times 180 degrees. For an octagon this is 180 x 6 with is 1080 degrees, thus: The sum of the interior angles of a regular octagon is 1080 degrees
ANY n-sided polygon has interior angles that sum to 180(n - 2) degrees. For an octagon this is 180 x 6 ie 1080 degrees (so the individual interior angles of a regular octagon are 135 degrees).
The 8 interior angles of an octagon add up to 1080 degrees.
6 because there are 1080 degrees in an octagon and 180 degrees in a triangle so 1080/180 = 6 triangles
It takes 6 triangles and 6*180 = 1080 degrees which are the total degrees in an 8 sided octagon
The sum of the internal angles of a n-gon are (n-2)*180 degrees. For an octagon, n = 8 so the sum of the internal angles is (8-2)*180 = 6*180 = 1080 degrees. If the octagon is regular, all eight of its internal angles are equal. So each of them equals 1080/8 = 135 degrees.
120 It is 135 degrees. ((8 x 180) - 360) / 8 = 135
An octagon has eight sides, which means it also has eight angles. The sum of the interior angles of any polygon can be found using the formula (n-2) * 180 degrees, where n is the number of sides. For an octagon, this would be (8-2) * 180 = 1080 degrees. Each angle in a regular octagon measures 135 degrees.
It is: (8-2)*180 = 1080 degrees
