The third Congruence Theorem that we will go over is ASA (Angle-Side-Angle).  This means that there are two angles and an included side that are respectively equal.  Let's look at the diagram below:
We can write a congruence statement from the diagram above by stating what we know.  We know that,
Since we know that two angles and the included side are congruent to the other triangle
​then we can conclude that:

Example

Given the following triangles, write a congruence statement to show that the triangles are congruent:
