Geometry for Elementary School/Congruence and similarity

In this section, we will talk about congruence and similarity, which are related to figures that look the same.

Before you start
Ask yourself these questions: If your answer to any of these questions is no, you should check out the previous chapters before you advance any further.
 * 1) How can one construct a triangle given only three dimensions?
 * 2) What are vertically opposite angles?
 * 3) How many conditions are there for two lines to be parallel?
