Understanding Right Triangles: Congruence and Theorems

In this lesson, you'll learn how to determine the congruence of right triangles using various tests. Our focus will include understanding the definitions of key terms such as hypotenuse and legs, as well as applying important theorems including SSS, SAS, ASA, and AAS to prove triangle congruence. Through practical exercises, you will practice identifying congruent triangles and understand the significance of these theorems in geometry. Get ready to enhance your skills in triangle congruence!
