Question

What statements about prisms are always true if the top base is directly above the bottom base?

The bases are congruent.
The bases can be any shape.
The lateral faces are rectangles.
The lateral faces are congruent.

Answer 1

The following are true:

1. The bases are congruent. This is what makes it a prism.

3. When the bases are polygons- which they should be for it to be a prism, the lateral faces are rectangles. This is always true because the edges of the polygon wil create a rectangle when it connects to the other edge on the opposite side of the prism.

Answer 2

The bases are congruent.

Explanation:

Two figures are said to be Congruent if both figures are identical in their shape and size that means both figures have the same shape and also they have some dimension.

Since, if the top base is directly above the bottom base then the bases must be congruent. So, the first option is only true here.

The lateral faces may be a rectangle or may not be. So, it is not the correct option.
