A triangular prism.
triangular polygon
a triangular pyramid
Quite possibly, a triangle.
A triangular prism has 9 edges and 6 corners. P.S. In math, corners are called vertices.
A tetrahedron is a 3-dimensional figure with four sides - i.e. a triangular pyramid.
a square pyramid (i found it in my sons math book !)
no im pretty sure that they only have 4 but come on man that's like 5th grade math A triangular prism has 5 faces, a triangular face on each end and three rectangular faces along its parallel sides.
In math pictures, there are several types of pyramids, primarily categorized by their base shapes. The most common types are triangular pyramids (tetrahedrons) with triangular bases, and square pyramids with square bases. Additionally, pyramids can have other polygonal bases, such as pentagonal or hexagonal. Each type of pyramid maintains a vertex at the apex, connecting to all vertices of the base, forming triangular faces.
In mathematics, a triangular prism is a three-dimensional geometric shape with two parallel triangular bases connected by three rectangular faces. The triangular bases can vary in size and shape, but they must be congruent. The height of the prism is the perpendicular distance between the two triangular bases. Triangular prisms are commonly studied in geometry and can be used to calculate volume and surface area.
