# What is SAS in Geometry?

In geometry, two shapes are congruent if they have the same size and shape. You can use a variety of methods to show that two shapes are congruent, including the Side-Angle-Side (SAS) criterion. In this blog post, we'll give you a step-by-step guide on how to use the SAS criterion to prove two triangles are congruent.

## How to Use the SAS Criterion

Step 1: Label the angles and sides of each triangle. It's important that you label each triangle exactly the same so that you can easily identify which side and angle corresponds to which in the other triangle.

Step 2: Compare the pairs of corresponding angles. If at least two pairs of angles are equal, then you can move on to Step 3. If not, then the triangles are not congruent.

Step 3: Compare the pairs of corresponding sides. If at least two pairs of sides are equal, then you can conclude that the triangles are indeed congruent.

And that's all there is to it! By following these simple steps, you can use the SAS criterion to determine whether or not two triangles are congruent.

## Conclusion:

The SAS criterion is a quick and easy way to show that two triangles are congruent. All you need to do is label the angles and sides of each triangle, compare the pairs of corresponding angles, and then compare the pairs of corresponding sides. As long as you can find at least two pairs that match up, you're good to go!

## FAQ

### What is the SAS criterion?

The SAS criterion is a way to show that two triangles are congruent by comparing the pairs of corresponding angles and sides. As long as you can find at least two pairs that match up, you can conclude that the triangles are indeed congruent.

### What does SAS mean in geometry?

SAS stands for Side-Angle-Side. It's a criterion that you can use to show that two triangles are congruent.

### What is SAS criterion Class 7?

The SAS criterion Class 7 is a way to show that two triangles are congruent by comparing the pairs of corresponding angles and sides. As long as you can find at least two pairs that match up, you can conclude that the triangles are indeed congruent.

### What is SAS in geometry examples?

There are a few different examples of SAS in geometry. One example is if you have two triangles that both have two sides that are equal, and the angle between those two sides is also equal. Another example is if you have two triangles that both have two angles that are equal, and the side between those two angles is also equal.
