The SAS (Side-Angle-Side) theorem is really helpful for showing that two triangles are the same. Here’s how it works:
What it means: If one triangle has two sides that are the same length as two sides of another triangle, and the angle between those sides is also the same, then the two triangles are congruent. That means they are exactly the same shape and size.
Why it’s important: This theorem lets us easily check if two triangles match without having to look at all three sides or angles. We only need to look at one angle and the two sides next to it!
Using the SAS theorem makes solving triangle problems a whole lot easier!
