## What were the 3 similarity postulates?

There are three triangle similarity theorems that specify under which conditions triangles are similar: If two of the angles are the same, the third angle is the same and the triangles are similar. If the three sides are in the same proportions, the triangles are similar.

## What is SSS and SAS postulate?

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 SSS similarity postulate?**

SSS Similarity Theorem: If all three pairs of corresponding sides of two triangles are proportional, then the two triangles are similar.

**What is SAS similarity postulate?**

SAS Similarity Theorem: If two sides in one triangle are proportional to two sides in another triangle and the included angle in both are congruent, then the two triangles are similar.

### Is SAS a postulate?

Side-Angle-Side Postulate This is called the Side-Angle-Side (SAS) Postulate and it is a shortcut for proving that two triangles are congruent. The placement of the word Angle is important because it indicates that the angle you are given is between the two sides.

### What is SSS ASA SAS AAS?

There are 5 main rules of congruency for triangles: SSS Criterion: Side-Side-Side. SAS Criterion: Side-Angle-Side. ASA Criterion: Angle-Side- Angle. AAS Criterion: Angle-Angle-Side.

**How are the SSS postulate and the SAS postulate alike?**

The similarity between these two postulate is that they both have congruent sides. They different because the S A S SAS SAS postulate also mentions the angle.

**What is SAS postulate?**

Postulate 12.2: SAS Postulate. If two sides and the included angle of one triangle are congruent to two sides and the included angle of a second triangle, then the triangles are congruent.

#### How are the SSS similarity theorem and the SSS congruence postulate alike How are they different?

How are the SSS ~ Theorem and the SSS Congruence Postulate alike? How are they different? Both involve all three sides of a triangle, but corresponding sides are proportional for SSS ~ and congruent for SSS Congruence.

#### What’s SSS in geometry?

SSS (side-side-side) All three corresponding sides are congruent. SAS (side-angle-side) Two sides and the angle between them are congruent.

**Is SSS a postulate or theorem?**

SSS Theorem (Side-Side-Side) Perhaps the easiest of the three postulates, Side Side Side Postulate (SSS) says triangles are congruent if three sides of one triangle are congruent to the corresponding sides of the other triangle. This is the only postulate that does not deal with angles.

**What is SSS math?**

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)
