the pyramide rectangular base has 12 sides.
One side in its base. !!!! However, a regular pentgon has five(5) equal length sides. One of those sides is the base line.
At least four, but it can be more. If the base is a triangle (three sides) add the base and you get four. if the base is a quadrilateral (four sides), add the base and you get five. However many sides the base has, add one.
a cone has one base and a circular top... therefore it has 2 sides and one corner
A triangle has three sides in total. If it has more than three sides, it is not a triangle. One of the three sides is called the 'base' ... usually the side that the triangle is resting on.
The base has three sides.
Five One base and four sides
An octagon is a plane figure. It has eight sides, but no real base.
It has six sides.
4 sides
A cone only has a base, no sides
A ___ pyramid is a pyramid with ___ as its base. In this case, we have a nonagon, a nine-sided polygon, as the base. So, if you imagine each edge of the nonagon as having one triangular side coming off of it, and all of the triangular sides meeting at a point over the base, you then have 9 sides, one for each edge, plus the base itself - 10 sides total.
