A Hexagonal Pyramid Is Located On Top Of A Hexagonal Prism. How Many Vertices Are There?
The sides of the heptagon must be straight and meet to form seven vertices which close in space. The seven sides of a heptagon meet, but do not intersect or cross.
Like other 2d shapes, the sides of a heptagon can be of different lengths, creating an irregular heptagon. or the sides are equal to form a regular heptagon
The diagonals. For convex heptagons, all diagonals lie within the shape. For concave heptagons, at least one diagonal is outside the shape.
Here is an image of a regular heptagon. A regular heptagon has seven congruent sides, seven vertices, and seven equal interior angles:

Here is an irregular heptagon, which means that its seven sides are not congruent and its seven interior angles are not equal:
Like other geometric shapes such as the octagon, hexagon and quadrilateral, heptagonal shapes can be found in man-made objects and in nature.

Apologies for the really basic question, however, I don’t really understand how to count edges/faces for these types of diagrams with “marked” vertices.
For instance. For Fig. 3.11, apparently $V=4$, but I don’t know how to compute $E$ and $F$. Specifically, there are two “bc” arcs, should we count both or just one? Also, ABC has two faces. It could be a Mobius strip, so $chi=V-E+F=0$.
Solved How Many Vertices And Edges In The Following Graph?
But there is one missing piece of information: should the edges along the outer border also be marked? For example, in Fig. 3.11, should the edge $a-b$ on the left side of the figure and the edge $a-b$ on the right side of the figure be identified as the same edge? Without more context, it’s impossible to tell. Maybe someone wrote some of the letters in Figure 3.11 and didn’t intend to identify themselves.
Now, in general, there’s a convention in these kinds of problems: pairs of outer boundary edges with identical endpoint labels must be identified as the same edge. Also, there is no facial recognition. You’ll find this convention spelled out in various textbook sources, and my guess is that it’s the intended convention in the book you got these images from, although you may have to read between the lines to make sure it’s the intended convention. .
BTW, if you follow these conventions you may or may not get “simple complex”, but you will always get “$Delta$-complex” (I’m using terminology from Hatcher’s book on algebraic topology).
In Fig. 3.11, the left and right edges $a-b$ are marked with 1 edge and are the only signs. Therefore, of the nine edges visible in Fig. 3.11, two of these nine are marked as 1 edge, the remaining seven of these nine form 7 edges after marking, for a total of $1+7=8$ edges managed after marking. The number of faces after identification is $4$.

In Fig. 3.13, the two left and right edges $a-d$ are marked with 1 edge, the left and right edges $d-c$ are marked with $1$ edge, the top and bottom edges $c-b$ are marked with $1$ edge, and the upper and lower borders $b-a$ are border marked $1. Marked at the border. None of the remaining eight inner edges are identified, creating 8 more edges after identification. After identification, this gives a total of $1+1+1+1+8=12$ edges. The number of faces after identification is $8$.
