# What Is Sss In Math?

## What does SSS mean in math?

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 is SSS SAS ASA AAS?

Congruent triangles are triangles that have the same size and shape. This means that the corresponding sides are equal and the corresponding angles are equal. In this lesson, we will consider the four rules to prove triangle congruence. They are called the SSS rule, SAS rule, ASA rule and AAS rule.

## What is an example of SSS?

The side – side – side rule ( SSS ) states that: Two triangles are congruent if their corresponding three side lengths are equal. Illustration: Triangle ABC and PQR are said to be congruent (△ABC ≅△ PQR) if length AB = PR, AC = QP, and BC = QR.

## What is the SSS rule?

SSS (Side-Side-Side) If all the three sides of one triangle are equivalent to the corresponding three sides of the second triangle, then the two triangles are said to be congruent by SSS rule.

## What do SSS mean?

## How do you prove triangles are similar?

If two pairs of corresponding angles in a pair of triangles are congruent, then the triangles are similar. We know this because if two angle pairs are the same, then the third pair must also be equal. When the three angle pairs are all equal, the three pairs of sides must also be in proportion.

## How do I know my SSS SAS ASA AAS?

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

1. SSS (side, side, side) SSS stands for “side, side, side” and means that we have two triangles with all three sides equal.
2. SAS (side, angle, side)
3. ASA (angle, side, angle)
4. AAS (angle, angle, side)
5. HL (hypotenuse, leg)

## How do you know if it’s AAS or ASA?

If two pairs of corresponding angles and the side between them are known to be congruent, the triangles are congruent. This shortcut is known as angle-side-angle ( ASA ). Another shortcut is angle-angle-side ( AAS ), where two pairs of angles and the non-included side are known to be congruent.

## How do you prove SAS Similarity Theorem?

SAS Similarity: If in two triangles, one pair of corresponding sides are proportional and the included angles are equal then the two triangles are similar.

1. Given: Two triangles ABC and DEF such that ∠A = ∠D.
2. Prove that: ΔABC ~ ΔDEF.

## What does the SSS postulate mean?

Side-Side-Side Or, if we can determine that the three sides of one triangle are congruent to three sides of another triangle, then the two triangles are congruent. We refer to this as the Side Side Side Postulate or SSS.

## How are SSS and SAS different?

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.

## What is the use of SSS?

Social Security System (SSS) SSS members can avail of maternity, sickness, disability, retirement, funeral and death benefits. SSS also allows qualified members to take up salary, housing, business, educational loans.

## Is AAA a postulate?

(This is sometimes referred to as the AAA Postulate —which is true in all respects, but two angles are entirely sufficient.) The postulate can be better understood by working in reverse order. The two triangles on grids A and B are similar, by a 1.5 dilation from A to B.

## Is AAA a thing in geometry?

Knowing only angle-angle-angle ( AAA ) does not work because it can produce similar but not congruent triangles. Because there are 6 corresponding parts 3 angles and 3 sides, you don’t need to know all of them.

## How do you find the SSS triangle?

To solve an SSS triangle:

1. use The Law of Cosines first to calculate one of the angles.
2. then use The Law of Cosines again to find another angle.
3. and finally use angles of a triangle add to 180° to find the last angle.
