text: When all angles are equal and all sides are equal it is regular, otherwise it is irregular
text: This is a regular octagon because all the angles and sides here are equal.
text: When an octagon has all equal sides and equal angles, then it is defined as regular octagon but with unequal sides and unequal angles, it is defined as an irregular octagon.
text: All the sides and all the angles are equal respectively.
text: The total sum of the interior angles is 1080°, where each angle is equal to 135°(135×8 = 1080)
text: All eight sides of an octagon are equal in length, and all eight angles are equal in size.
text: If the 8 sides of the octagon are equal in length and the angles between these sides are equal, the octagon is called a regular octagon.
text: All the sides are equal in length and all the angles are equal in measurement.
text: If the octagon is a regular octagon (all eight sides and all eight angles are equal), then it is a regular polygon.
text: Equal side lengths isn't enough--the angles need to be equal, too.
text: that is, if and only if all the sides have the same length and all the angles are equal.
text: Since the angles are equal, we can divide the sum of the angles by five.
text: The other two angles must be equal: call them x.
text: The other two angles are equal: call them each x.
text: If the octagon is a regular octagon (all eight sides and all eight angles are equal), then it is a regular polygon.
text: If the octagon is a regular octagon (all eight sides and all eight angles are equal), then it is a regular polygon.
text: Also, I am sure you will agree that symmetry, the acute angles of the small triangle must be equal (so it is a right triangle, but also an isosceles triangle).
text: That is one where the angles are all equal and the sides are all equal.
text: If the sides are all the same length, and the angles are all equal, it is a regular octagon.
text: This means that each interior angle of the regular octagon is equal to 135 degrees.
text: Each exterior angle is the supplementary angle to the interior angle at the vertex of the polygon, so in this case each exterior angle is equal to 45 degrees.
text: If the octagon is a regular octagon (all eight sides and all eight angles are equal), then it is a regular polygon.
text: A regular octagon has eight equal sides and equal angles.
