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

rectangular pyramid
square pyramid
triangular pyramid
tetrahedron

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! :)
