There are 4 triangles that make up a pyramid. 4 on the sides and on the bottom a square or rectangle.
The only thing I can come up with would be a tetrahedron. You could make a pyramid with a square (open) base, I guess.
An octagonal pyramid has 9 vertices. The base of this shape is an octagon, which will give it 8 vertices when the triangles that form the sides are considered. Those triangles will lead up to the apex (top) of the pyramid, and that will be the 9th vertex.
pentagons and triangles-if i'm right, you get to answer this :Dwhat is a+b(4-2)if a=-6, if b=8it's easy, dont worry.
triangles

They can be any kind of triangles.
Five. Four triangles and one square make up a square pyramid.
Triangles (four of) and a square.One square as base and four triangles as sides.
One square and four triangles.
A rectangle and 4 triangles.
Yes. They have perpendicular bisectors in the four triangles that make up four of the five sides of a square-based pyramid
4. 1 at the bottom and 3 joininq on to it. Simples.
a pentagonal pyramid is a shape with a base of a triangle, and triangles forming up to the point
They are both 3d and they both form triangles on the sides to come up and make a point
rectangular pyramid
A polygon with n sides, and n triangles, where n ≥ 3. Most commonly, the polygon at the base is a triangle or a square. If the base polygon is regular and the pyramid is a right pyramid (ie apex above the centre of the basal polygon), the triangles will be isosceles.
