Yes each angle is 135o
Whether it is a regular or irregular octagon does not matter. An octagon is, by definition, a 2-dimensional figure with eight sides, and therefore with eight angles. A regular octagon will have eight equal angles and an irregular octagon will have eight angles some of which are not equal to the others.
A regular octagon has eight equal angles. An irregular octagon need not have any equal angles, although it may have some.
Yes. A regular octagon must have equal angles, but an irregular octagon cannot have all its angles equal
An octagon has eight sides. A regular octagon is one that has eight sides of equal length, and all the angles are of the same measure. Anything else - sides that are not all the same length, or not all angles the same - would be a non-regular octagon.
A shape with eight sides is always an octagon. If all angles and sides are equal, it is called a regular octagon.
No, it is not necessary. Only a regular octagon needs to have equal sides and angles.
8 if it's an regular octagon
Any 8 sided polygon is called an octagon. If all of the sides and angles are equal, then it's called a regular octagon.
8
Both, in a way. An octagon gets its name from the word meaning, "eight angles" so an octagon can have eight unequal sides. However, a regular octagon is a closed eight-sided figure with sides of the same length and internal angles of the same size.
basicly regular octagon No, it's a hexagon. An octagon has 8 equal sides and 8 equal angles.
An octagon can be an irregular shape, but a regular octagon has all sides and angles equal.
