Extrinix · Answer

Do you understand what CPCTC is?

babygirlAzia · Answer

yes

Lul · Answer

LAM ≅ ∠LBM is CPCTC

∠LMA ≅ ∠LMB should be right if your trying to get CPCTC

Extrinix · Answer

Alright, so you know how $\triangle ALM \cong \triangle BLM$

they both share 2 points ( $L$ and $M$ )
meaning that makes $\angle$A and $\angle$B similar angles,
making $\angle$LAM $\cong$ $\angle$LBM

$\angle$LAM being $\cong$ to $\angle$LBM makes all of the corresponding sides $\cong$ to the other $\triangle$

maybe an image will help understanding more easy

CPCTC mean  "Corresponding Parts of Congruent Triangles are Congruent"

York · Answer

the third one cuz its congruent in the order in which the points are, if that makes sense; like, point A corresponds to B, L to L, and M to M. |dw:1619533043855:dw|
