But bro for proving triangle BAC and BLA there should be 3 conditions. U have written two only!!
And what is this ~~~~
~ ??
similarity .If in two triangles two angles are equal.then they are similar .
Ok.. can't we do like this -
Given: ABC is right triangle right angled at A and AL ⊥ BC
Now, in ΔBAL and ΔBCA
∠ABL = ∠CBA (Common)
∠BLA = ∠BAC = 90°
So, ΔBAL ∼ ΔBCA (by AA similarity criteria)
⇒ ∠BAL = ∠ACB (C.P.C.T)
