Which best describes the three-dimensional figure that can be made from the net shown?

Last option.

Step-by-step explanation:

By definition, a pyramid has a base (which is a polygon) and three or more triangular faces.

You can observe in the image that the the figure has three triangular faces and a triangular base. The sides of the base are all equal, then it is an equilateral triangle.

Then, since the base of the tringular pyramid is an equilateral triangle, the faces are also equilateral triangles.

Therefore, the three-dimensional figure that can be made from the net shown, is:

A triangular pyramid that must have 4 congruent and equilateral triangles.

"D"

Step-by-step explanation: The net shown here is composed of three triangular faces and one triangular bases. The triangular faces tell us that the figure is a pyramid and the triangular base tells us that the net is a triangular pyramid.

The base of a triangular pyramid is an equilateral triangle, which means that the faces are also equilateral triangles.
