The term octagon means an 8 sided geometrical figure; if the sides are all the same length and the angles are all identical, it is then called a regular octagon. Irregular octagons are also possible.
Yes
Yes. A regular octagon must have equal angles, but an irregular octagon cannot have all its angles equal
a hexagon could be adjacent only if it is regular an octagon is adjacent
A regular octagon has eight equal angles. An irregular octagon need not have any equal angles, although it may have some.
A shape with equal adjacent angles is a rhombus. In a rhombus, all four sides are of equal length, and each pair of adjacent angles are equal. This means that opposite angles are also equal, resulting in a symmetrical shape. Other shapes with equal adjacent angles include rectangles and squares, where adjacent angles are 90 degrees.

In a trapezium (or trapezoid in American English), adjacent angles are not necessarily equal. However, in an isosceles trapezium, the angles adjacent to each leg are equal. In general, the properties of the trapezium do not require adjacent angles to be equal.
No, it is not necessary. Only a regular octagon needs to have equal sides and angles.
A octagon has 8 angles An octogon has 8 equal angles and 8 equal sides.
Rectangles have congruent adjacent angles.
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.
An octagon has 8 sides and 8 angles. The sum of the interior angles of an octagon is 1080 degrees.
basicly regular octagon No, it's a hexagon. An octagon has 8 equal sides and 8 equal angles.
