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

- SSS (side, side, side) SSS stands for "side, side, side" and means that we have two triangles with all three sides equal. ...
- SAS (side, angle, side) ...
- ASA (angle, side, angle) ...
- AAS (angle, angle, side) ...
- HL (hypotenuse, leg)

On top of, what are the 4 ways to prove triangles are congruent?

Two triangles are said to be congruent if and only if we can make one of them superpose on the other to cover it exactly. These four criteria used to test triangle congruence include: **Side – Side – Side (SSS), Side – Angle – Side (SAS), Angle – Side – Angle (ASA), and Angle – Angle – Side (AAS)**.

On top of everything, how do I prove my SSS SAS ASA AAS?

In any case, what is the ASA formula?

ASA formula is one of the criteria used **to determine congruence**. ... "if two angles of one triangle, and the side contained between these two angles, are respectively equal to two angles of another triangle and the side contained between them, then the two triangles will be congruent".

Is AAS congruent?

The Angle Angle Side postulate (often abbreviated as AAS) states that if two angles and the non-included side **one triangle are congruent to two angles** and the non-included side of another triangle, then these two triangles are congruent.

"AAA" means "**Angle, Angle, Angle**" "AAA" is when we know all three angles of a triangle, but no sides.

In geometry, two figures or objects are congruent **if they have the same shape and size**, or if one has the same shape and size as the mirror image of the other.

The SSS Theorem **If the three sides of one triangle are equal to the three sides of another triangle, the triangles are congruent**.

Therefore, you can prove a triangle is congruent whenever you have any two angles and a side. ... Angle-Angle-Side (AAS or SAA) Congruence Theorem: **If two angles and a non-included side in one triangle are congruent to two corresponding angles and a non-included side in another triangle, then the triangles are congruent**.

SSS or Side-Side-Side congruence rule states that **if three sides of one triangle are equal to three corresponding sides of another triangle, then the triangles are congruent**.

What is the HL Postulate? The HL Postulate states that **if the hypotenuse and leg of one right triangle are congruent to the hypotenuse and leg of another right triangle, then the two triangles are congruent.**

Side-Angle-Angle (SAA) Are **two triangles congruent** if one side, an adjacent angle, and the opposite angle of one triangle are congruent, respectively, to one side, an adjacent angle, and the opposite angle of the other triangle?

Therefore, SSA (Side-Side-Angle) **is NOT a congruence rule**.

Four shortcuts allow students to know two triangles must be congruent: SSS, SAS, ASA, and AAS. ... Knowing **only angle-angle-angle (AAA) does not work because it can produce similar but not congruent triangles**.

Theorem 12.2: The AAS Theorem. **If two angles and a nonincluded side of one triangle are congruent to two angles and a nonincluded side of a second triangle, then the triangles are congruent**....Geometry.StatementsReasons

Angle-Angle-Side Postulate (AAS) The AAS Postulate says that **if two angles and the non-included side of one triangle are congruent to two angles and the non-included side of a second triangle, then the triangles are congruent**.

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

Definition: **Triangles are similar if the measure of all three interior angles in one triangle are the same as the corresponding angles in the** other. This (AAA) is one of the three ways to test that two triangles are similar . ... And so, because all three corresponding angles are equal, the triangles are similar.

Angle Angle Angle (AAA) **If two angles of one triangle are respectively equal to two angles of another triangle, then the two triangles are similar**. It is sufficient to prove that only two pairs of angles are respectively equal to each other.

In pre-algebra, y is **a variable**. It holds the place of number that we may not know just yet. Because no one should have to say, "I was never any good at math." y is a variable just like x is a variable.

- The three sides are equal (SSS: side, side, side)
- Two angles are the same and a corresponding side is the same (ASA: angle, side, angle)
- Two sides are equal and the angle between the two sides is equal (SAS: side, angle, side)

In other words, **two triangles are congruent if the sides and angles of one triangle are equal to the corresponding sides and angles of the other triangle**. ...

Given two sides and non-included angle (SSA) **is not enough to prove congruence**. ... You may be tempted to think that given two sides and a non-included angle is enough to prove congruence. But there are two triangles possible that have the same values, so SSA is not sufficient to prove congruence.

Angle-Side-Angle (ASA) Rule Angle-side-angle is a rule used to prove whether a given set of triangles are congruent. The ASA rule states that: **If two angles and the included side of one triangle are equal to two angles and included side of another triangle, then the triangles are congruent**.
