trapezoid
The sides are triangular in shape.
Square Pyramid
A triangular dipyramid.
A tetragon or a quadrilateral, like a square or rectangle.
A shape with a square base and four triangular sides is a pyramid.
Pyramids are classified by the shape of their base. A triangular pyramid has a triangular base and three triangular side faces. A square pyramid has a square base and four triangular sides. A pentagonal pyramid has a pentagonal base and five triangular sides. A hexagonalpyramid has a hexagonal base and six triangular sides, and so on.
Square pyramids have a square base and four triangular faces, while triangular pyramids have a triangular base and three triangular faces. The number of sides and the shape of the base are the main distinguishing factors between the two types of pyramids. Additionally, the angles and dimensions of the faces will vary based on the shape of the base in each type of pyramid.
A Square Pyramid.
A pentagon has fives sides, or if you mean a three dimensional shape, a pyramid has five sides, four triangular and one square.
a triangular pyramid is a shape with 5 sides and looks like a triangle just 3d wall a square pyramid has 6 sides and is like a square just 3d
A shape with 5 sides is a pentagon.However, the term face is only applied to three-dimensional forms,and a shape (solid) with 5 faces is a pentahedron.There are no regular pentahedrons. The two forms are the square pyramid and the triangular prism. The former has 4 triangular sides and a square or rectangular base; the latter has 3 rectangular (or square) faces and two triangular ends.
Four sides ⇒ it is a tetrahedron. More commonly, it is called a triangular pyramid.
