Recall the definition of each concept to check if it fits the figure.
A) Square: A square is a quadrilateral whose sides all have the same length.
B) Polygon: A polygon is a 2D shape formed by non-intersecting straight segments.
C) Triangle: A triangle is a polygon with exactly 3 sides.
D) Polyhedron: A polyhedron is a 3D shape formed by flat polygonal shapes.
E) Pyramid: A pyramid is a polyhedron formed by a simple polygon whose lateral faces are triangles that converge in a common vertex.
F) Prism: A prism is a polyhedron formed by two parallel and equal polygonal faces, whose lateral faces are parallelograms.
The given object is a 3D shape formed by flat polygonal shapes, with a base that is a quadrilateral and whose lateral faces are triangles that converge in a common vertex.
Therefore, the only two terms that correcty describe the given object are:
D) Polyhedron
E) Pyramid
