In that previous, the triangles were shown to be congruent directly as a result of their sharing two equal corresponding sides and one equal included angle. Throughout a direct proof, the statements that are made are specific examples of more general situations, as is explained in the "reasons" column.

## How to write proofs in geometry

In mathematics, a proof is a deductive argument for a mathematical statement. Understanding the Problem Formatting a Proof Writing the Proof Community Q&A Mathematical **proofs** can be difficult, but can be conquered with the proper background knowledge of both mathematics and the format of a proof.

Observations, measurements, and experimentations are not proof If a formula works for 1 million specific examples, this is still not a proof Understanding a proof can be a daunting task.

#### How to write proofs in geometry

A common strategy for __geometry__ __proofs__ is approaching the steps in backwards order. When we previously discussed inductive reasoning we based our reasoning on examples and on data from earlier events.
