science space and astronomy# What is SSS SAS AA?

Last Updated: 2nd January, 2020

**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)

Also know, what is SSS and SAS in geometry?

If all three pairs of corresponding sides are congruent, the triangles are congruent. 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.

Likewise, how do you determine if there are two triangles? We need to find the measure of angle B using the Law of Sines: **If** their sum is less than 180°, we **know** a **triangle** can exist. To **determine if there** is a 2nd valid angle: See **if** you are given **two** sides and the angle not in between (SSA). This is the situation that may have 2 possible answers.

Subsequently, one may also ask, what does AA mean in geometry?

**AA** stands for "angle, angle" and **means** that the triangles have two of their angles equal.

How do you find a SAS triangle?

"**SAS**" is when we know two sides and the angle between them. use The Law of Cosines to **calculate** the unknown side, then use The Law of Sines to **find** the smaller of the other two angles, and then use the three angles add to 180° to **find** the last angle.
