Answer:
AAS
Step-by-step explanation:
Here is the setting out proof with a - side note:
In Triangle JLM and Triangle JLK
Angle K is equal to Angle M (given) - This is a pair of matching angles
JK = JM (given) - This is a pair of matching sides
Since JL bisects KLM, Angle KLJ = Angle MLJ (Bisect means it cuts it in half, meaning the angle has been divided into two equal parts) - This is a pair of matching angles.
Therefore, Triangle JLM and Triangle JLK are congruent (AAS) - The reason why we do AAS is because we have two pairs of matching angles and a pair of sides are equal. It is call AAS and not ASA, unknown reason but that is just how it is.
