An OCTAGON
square
In the case of polygons (basically the simplest case), you need to determine that corresponding sides are proportional (for example, all sides in figure "B" are twice as large as the corresponding sides in figure "A"), and that corresponding angles are equal.
A pyramid has one more corner and faces than the number of sides in its base; thus a decagonal pyramid has 10 + 1 = 11 faces and corners. A pyramid has twice as many edges as sides in its base; thus a decagonal pyramid has 2 X 10 = 20 edges.
a hexagon
No. Adjacent sides, yes. (Twice the sum)
A figure with twice as many sides as a triangle would be a hexagon. Also known as a 6 sided figure.

"Bisect" means to divide a shape into 2 equal parts. One case where 2 intersecting quadrilaterals bisect each other, is when they are both rectangles, twice as long as they are wide. They could intersect to overlap in way that made 3 squares. One of the squares would be in common. This could be done with the rectangles either lined up, or at right angles.This can also work with 2 identical (or mirrored) parallelograms, where the longer sides are exactly twice as long as the short sides. They could overlap at the ends (in 2 ways, depending whether they are identical or mirrored) to have a rhombus in common. Rectangle, rhombus and square are special cases of parallelogram.When putting questions from school into Answers, be sure to use the same wording. Perhaps "bisect" was not the word.2 quadrilaterals that are of different sizes can not bisect each other.Some quadrilaterals have sides which are all of different lengths.Kite shapes are also quadrilaterals.
A triangular based pyramid would have 4 corners; three for the triangular base and one for the peak. A pyramid has twice as many edges as sides in its base; thus a triangular pyramid has 2 × 3 = 6 edges. A triangular based pyramid is called a tetrahedron.
A Square has 4 sides, the shape you want that has twice as many sides as this is called a Octagon. ( Oct = 8 - as in Octopus ).
Yes. Rather a convoluted way of saying it, but it is true.
octagon-8 sides
Basically to see around corners, do it twice and you have the device that's common on submarines.
An heptagon has 7 sides and 14 diagonals
a hexagon
