It depends on the base. If the base is an n-sided regular polygon, the pyramid will have n/2 pairs of parallel sides. The number of parallel sides when the base is irregular will depend on the exact details of the base.
Its a 49 sided polygon.
An n-sided polygon or n-gon, just like it sounds, has n sides. For example, a 13-sided polygon has 13 sides. A 24-gon has 24 sides.
If the polygon is also a quadrilateral (4 sided polygon) then the answer is trapezoid. But there are many multi-sided polygons that could have a pair of opposite parallel sides - hexagon for example or consider the following pentagon: /\ | | -- That was difficult, but you get the idea. It looks like a house.
None.
5 pairs of parallel sides.
None.

A 3-sided polygon has 0 parallel sides. A 4-sided polygon can have 0, 2 or 4 parallel sides. A 5-sided polygon can have 0, 2, 3 or 4 parallel sides. In general, an n-sided polygon can have 0, 2, 3, ..., n-1, or n parallel sides where n>5. A polygon with n sides can have n pairs of parallel sides (if n is even) or (n-1)/2 pairs if n is odd AND greater than 3. But it need not have any.
None. (As there are an odd number of sides, each side is opposite a vertex and there are no parallel sides.)
A 40-sided polygon has 40 sides. Count again, to be sure.
It depends on the base. If the base is an n-sided regular polygon, the pyramid will have n/2 pairs of parallel sides. The number of parallel sides when the base is irregular will depend on the exact details of the base.
Uhh, 10 sides. It's a TEN SIDED POLYGON and you're asking how many sides it has? You answered the question yourself.
A 7 sided polygon is called a heptagon or a septagon.
It has 14 sides! The regular polygon with 14 sides is called a tetradecagon.
Exactly 10732 sides.
