Answer 1

The following statement is true: At least two of the lateral faces are congruent.

Because the words "at least" are used this means that at a minimum 2 of the faces are congruent. Because the base is in the shape of a triangle, this will definitely be true. The sides directly across from each other will be congruent and if the base is a square (which is also defined as a rectangle) than all 4 sides would be congruent.

Answer 2

At least two of the lateral faces are congruent. This is the true statement.

Explanation:

The correct statement is : At least two of the lateral faces are congruent.

A rectangular pyramid is a 3-D shape that has a rectangular base. Each corresponding side with respect to base, contains triangular faces. The triangular faces are called lateral faces and they meet at the apex. These faces are congruent to each other.
