## Are the triangles congruent by SSS or SAS?

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 SAS ASA and SSS congruence?

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)

#### How do you tell if a triangle is SAS or SSS?

1. SSS stands for “side, side, side” and means that we have two triangles with all three sides equal.
2. SAS stands for “side, angle, side” and means that we have two triangles where we know two sides and the included angle are equal.

How do you prove SAS?

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.

What does ASA SAS and SSS prove?

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 does a SAS triangle look like?

The SAS theorem states that two triangles are equal if two sides and the angle between those two sides are equal. In this diagram, if angle C = angle X, and side a = side z and side b = side y, then by the SAS theorem, these two triangles would be equal.

### What is SAS rule?

SAS (Side-Angle-Side) If any two sides and the angle included between the sides of one triangle are equivalent to the corresponding two sides and the angle between the sides of the second triangle, then the two triangles are said to be congruent by SAS rule.

#### How do you prove SAS similarity?

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.

What is SSS mean in comparing triangles?

SSS stands for “side, side, side” and means that we have two triangles with all three pairs of corresponding sides in the same ratio. If two triangles have three pairs of sides in the same ratio, then the triangles are similar.

Which triangles are congruent according to the SAS criterion?

The pair of triangles that are congruent by the ASA criterion isΔ ABC and Δ XYZ. The pair of triangles that are congruent by the SAS criterion is Δ BAC and ΔRQP.

## Does SSA guarantees congruence between two triangles?

If two triangles satisfy the SSA condition and the length of the side opposite the angle is greater than or equal to the length of the adjacent side (SSA, or long side-short side-angle), then the two triangles are congruent.

### How do you prove SSS theorem in similar triangles?

Part 3 of 4: Using the Side-Side-Side Theorem Define the Side-Side-Side (SSS) Theorem for similarity. Two triangles would be considered similar if the three sides of both triangles are of the same proportion. Measure the sides of each triangle. Using a ruler, measure all three sides of each triangle. Calculate the proportions between the sides of each triangle.

Are the triangles congruent by SSS or SAS? 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 SAS ASA and SSS…
