It is simply a closed seven-sided plane figure, bounded by seven straight lines, each of the same length. There is no requirement for the angles to be the same - in fact the shape can be concave.
heptagon and an equilateral triangle
Well, isn't that just a happy little challenge! To make a heptagon out of six equilateral triangles, you can start by arranging the triangles in a circular pattern with their edges touching. Then, you can add a seventh equilateral triangle on top to complete the shape. Remember, there are no mistakes, just happy accidents in art!
A seven-sided shape (polygon) is called a heptagon.
a heptagon is a dog
A heptagon is a seven-sided polygon.

No.
heptagon and an equilateral triangle
A regular heptagon is a polygon with seven equilateral sides. The shape must also be equiangular and convex.
None but there are 6 in a regular hexagon
You can fit 7 regular/equilateral triangles inside a Heptagon since a Heptagon has got 7 sides and vertices.
That depends on the type of triangle it is but if it's an equilateral triangle then its exterior angle is greater than that of a regular heptagon
If they are both regular then the 7 sided heptagon has a larger interior angle than a 3 sided equilateral triangle.
Join the 6 triangles like pizza slices
Perimeter = 7*24 = 168 cm
No. Equilateral heptagons (7 sided figures) do not tessellate the plane. Not if no other polygons are allowed. But if you allow a (non-equilateral) pentagon then you might be able to tessellate the plane!
It is the equilateral triangle that has the largest exterior angle of 120 degrees
