Question

which of the following terms correctly describe the object below? check all that apply. a. polygon b. pyramid c. square d. prism e. triangle f. polyhedron

Explanation:

Step1: Recall definitions

A polygon is a 2 - D shape. The given object is 3 - D, so it's not a polygon.

Step2: Analyze pyramid

A pyramid has a base and triangular faces that meet at a vertex. The given object has a base and triangular faces meeting at a vertex, so it is a pyramid.

Step3: Consider square

A square is a 2 - D shape. The given object is 3 - D, so it's not a square.

Step4: Examine prism

A prism has two congruent bases and rectangular lateral faces. The given object doesn't have two congruent bases and rectangular lateral faces, so it's not a prism.

Step5: Think about triangle

A triangle is a 2 - D shape. The given object is 3 - D, so it's not a triangle.

Step6: Evaluate polyhedron

A polyhedron is a 3 - D shape with flat polygonal faces, straight edges and vertices. The given object meets these criteria, so it is a polyhedron.

Answer:

B. Pyramid, F. Polyhedron
