It is possible to find geometry answer guides online, but it is important to recognize that as mathematics textbooks are updated, details in problems sometimes change. It is necessary to ensure that the editions match.

Generally, answer guides for geometry and other mathematics topics are not readily available to students in order to promote learning rather than cheating; however, parents sometimes find that access to an answer key is helpful for understanding how to work out a problem. Because geometry includes the challenging concept of proofs, parents may find that it is helpful to maintain good communications with a teacher in order to address concerns and difficulties.
