Question

Bryanne bought a loaf of bread that is shaped

Answer 1

Answer:

 Rectangle

Triangle

Step-by-step explanation:

Since you did not provide enough information, I will give you a general explanation assuming that she made these two cuts: a cut  perpendicular to the base of the rectangular prism and a cut at the corner.

For this exercise it is important to remember the definition of a "Cross section".

A cross section is defined as the shape obtained when a 3-dimensional figure is cut by a plane.

In this case, according to the information provided in the exercise, you know that:

- The loaf of bread Bryanne bought is a rectangular prism (This is the "3-dimensional figure").

- Bryanne cut it (The tool she used to cut it is the "plane")

Then:

 1. If Irene made the cut perpendicular to the base of the rectangular prism, the cross-section obtained would be: A RECTANGLE.

2.  If Irene made the cut at any corner of the rectangular prism,  the cross-section obtained would be: A TRIANGLE (Observe the picture attached to understand that intersection).
