Describe the two-dimensional shape created by slicing a rectangular pyramid parallel to the base.

Option 1: rectangle
Option 2: triangle

It's option 1

Option 1: rectangle

When a rectangular pyramid is sliced parallel to the base, the resulting two-dimensional shape will be a rectangle. The shape will have the same length as the base of the pyramid and the same width as the top face of the pyramid.

Option 2: triangle

If a rectangular pyramid is sliced parallel to the base and close to the apex, the resulting two-dimensional shape may be a triangle. The shape will have the same base as the rectangular pyramid but with a smaller height, creating a triangular shape.
