## What words in geometry are hard to define?

There are, however, three words in geometry that are not formally defined. These words are point, line and plane, and are referred to as the “three undefined terms of geometry”.

## What are the 3 proofs?

Three Forms of Proof

• The logic of the argument (logos)
• The credibility of the speaker (ethos)
• The emotions of the audience (pathos)

## What are the 3 kinds of proof?

There are many different ways to go about proving something, we’ll discuss 3 methods: direct proof, proof by contradiction, proof by induction. We’ll talk about what each of these proofs are, when and how they’re used. Before diving in, we’ll need to explain some terminology.

## How do you write a geometric proof?

Writing a proof consists of a few different steps.

1. Draw the figure that illustrates what is to be proved.
2. List the given statements, and then list the conclusion to be proved.
3. Mark the figure according to what you can deduce about it from the information given.

## What do parallel lines mean in proofs?

Two lines cut by a transversal are parallel if and only if alternate interior angles are congruent. Theorem 3-6 If two lines are cut by a transversal and same-side interior angles are. supplementary, then the lines are parallel.

## What are some examples of postulates?

A postulate is a statement that is accepted without proof. Axiom is another name for a postulate. For example, if you know that Pam is five feet tall and all her siblings are taller than her, you would believe her if she said that all of her siblings are at least five foot one.
