Question

question 2 of 25
the bases for a cylinder must be two discs that are parallel and:
a. similar.
b. congruent.
c. have one lying directly above the other.
d. squares.

Explanation:

A cylinder has two circular bases. By definition, these bases are parallel and congruent (same size and shape). Similar would mean same shape but not necessarily same size. One lying directly above the other is part of the cylinder's structure but the key property about the bases themselves is congruence. And the bases are circles, not squares.

Answer:

B. congruent.
