## What are 5 ways to prove a triangle?

There are five ways to find if two triangles are congruent: SSS, SAS, ASA, AAS and HL.

**How do you do a proof?**

The Structure of a Proof

- Draw the figure that illustrates what is to be proved.
- List the given statements, and then list the conclusion to be proved.
- Mark the figure according to what you can deduce about it from the information given.
- Write the steps down carefully, without skipping even the simplest one.

### How do you do proofs easily?

Practicing these strategies will help you write geometry proofs easily in no time:

- Make a game plan.
- Make up numbers for segments and angles.
- Look for congruent triangles (and keep CPCTC in mind).
- Try to find isosceles triangles.
- Look for parallel lines.
- Look for radii and draw more radii.
- Use all the givens.

**What does AAS mean in math?**

angle-angle-side

AAS (angle-angle-side) Two angles and a non-included side are congruent.

#### What are the 3 types of proofs?

Three Forms of Proof

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

**Are geometry proofs hard?**

It is not any secret that high school geometry with its formal (two-column) proofs is considered hard and very detached from practical life. Many teachers in public school have tried different teaching methods and programs to make students understand this formal geometry, sometimes with success and sometimes not.

## How do triangle proofs work?

The simplest way to prove that triangles are congruent is to prove that all three sides of the triangle are congruent. When all the sides of two triangles are congruent, the angles of those triangles must also be congruent. This method is called side-side-side, or SSS for short.

**What does SSS stand for in math?**

side-side-side

key idea

SSS (side-side-side) All three corresponding sides are congruent. | SAS (side-angle-side) Two sides and the angle between them are congruent. |

ASA (angle-side-angle) Two angles and the side between them are congruent. | AAS (angle-angle-side) Two angles and a non-included side are congruent. |

### What does SSS prove?

SSS (Side-Side-Side) The simplest way to prove that triangles are congruent is to prove that all three sides of the triangle are congruent. When all the sides of two triangles are congruent, the angles of those triangles must also be congruent. This method is called side-side-side, or SSS for short.
