Question

Which of the following best describes the pyramid represented by this net?

rectangular pyramid
square pyramid
triangular pyramid
tetrahedron

Answer 1

Tetrahedron best describes the pyramid represented by this net.

Answer 2

Step 1) Look at the base

We can see that the base is a square, so most likely then this net is a pyramid.

Step 2) Look at the sides

We can see that there are 4 sides, and they are triangles.

By definition, a triangular pyramid only has 3 sides, which we know because it has 'triangle' in its name. But, the tetrahedron has 4 sides, which we know because it has the prefix 'tetra' in it, which means 4.

The correct answer is tetrahedron.

Hope this helps! :)
