# What is SSS SAS SSA?

## What is SSS SAS SSA?

SSS stands for “side, side, side” and means that we have two triangles with all three sides equal. If three sides of one triangle are equal to three sides of another triangle, the triangles are congruent. SAS (side, angle, side)

## Can you apply SSA rule instead of SAS give reason?

Knowing only side-side-angle (SSA) does not work because the unknown side could be located in two different places. Knowing only angle-angle-angle (AAA) does not work because it can produce similar but not congruent triangles. The same is true for side angle side, angle side angle and angle angle side.

Is SSA a thing?

The acronym SSA (side-side-angle) refers to the criterion of congruence of two triangles: if two sides and an angle not include between them are respectively equal to two sides and an angle of the other then the two triangles are equal.

Is SAS a postulate?

Side Angle Side Postulate The SAS Postulate tells us, If two sides and the included angle of a triangle are congruent to two sides and the included angle of another triangle, then the two triangles are congruent.

### Why is there no SSA?

What about SSA (Side Side Angle) theorem? There is NO SUCH THING!!!! The ASS Postulate does not exist because an angle and two sides does not guarantee that two triangles are congruent. This is why there is no Side Side Angle (SSA) and there is no Angle Side Side (ASS) postulate.

### Can you prove congruence with SSA?

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.

Is SSA similar?

Is SSA a thing in geometry?

The SSA condition (side-side-angle) which specifies two sides and a non-included angle (also known as ASS, or angle-side-side) does not by itself prove congruence.

## What is the difference between SSS and SAS?

The difference is this: SSS means side-side – side. We need all three sides of the triangle congruent to call the entire triangle congruent. –. ASA means angle – side – angle. We need two angles and the included side, or side between two angles to be congruent before we can call the triangles congruent. –. SAS means side-angle-side.

## What does SSA mean In geometry?

“SSA” means “Side, Side, Angle”. “SSA” is when we know two sides and an angle that is not the angle between the sides. To solve an SSA triangle. use The Law of Sines first to calculate one of the other two angles; then use the three angles add to 180° to find the other angle;

What is SSS and SAS?

SSS and SAS – Concept. This congruence shortcut is known as side-side-side (SSS). Another shortcut is side-angle-side (SAS), where two pairs of sides and the angle between them are known to be congruent. SSS and SAS are important shortcuts to know when solving proofs. If two triangles are congruent, if I say that triangle abc…
