medical health lung and respiratory health# How are SAS and SSA different?

Last Updated: 11th April, 2020

**difference**is that in

**SAS**, the congruent angle is the one that is formed by the two congruent sides (as you see, the "A" is between the two S), whereas with

**SSA**, you know nothing about the angle formed by the two

Hereof, what is SSS SAS ASA AAS?

**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)

Likewise, is SAS a unique triangle? It is important to note that **SAS** construction will always produce one, **unique triangle**. It does not matter how much you flip, rotate or move the **triangle**, the measurements will not change. Even though the **triangle** may "look" different, it still has the same angle measures and side lengths.

Furthermore, how can you tell the difference between AAS and ASA?

**A.S.A.** refers to an angle, then side, then an angle in anticlockwise or clockwise direction; while **A.A.S.** refers to an angle, then angle, then a side in anticlockwise or clockwise direction. The former means that the side and two angles related to that side.

What is SAS rule?

Side-Angle-Side is a **rule** used to prove whether a given set of triangles are congruent. The **SAS rule** states that. If two sides and the included angle of one triangle are equal to two sides and included angle of another triangle, then the triangles are congruent. An included angle is an angle formed by two given sides.
