using congruence rule
Step-by-step explanation:
Given: ΔSAL, SA = LA and AT is the bisector of
To prove:
Proof:
Two triangles are congruent if they have same shape and same size.
Consider triangles ALT and AST
AL = AS
As AT bisects ,
AT = AT (common side)
So, ( by SAS congruence rule )
Here, SAS denotes side-angle-side
(using corresponding parts of congruent triangles)
Hence proved
