Question

please tell the answer​

Answer 1

Answer:

In thee fig., angle BAC=angleDAC

angleACD=angleACB

AC=AC(COMMON SIDE)

THEREFOTE THEY ARRE CONGRUENT

Answer 2

GIVEN : ∠1 = ∠2, ∠3 = ∠4

TO PROVE : Δ ABC ≅ Δ ADC

PROOF :

In Δ ABC & Δ ADC,

∠1 = ∠2 (Given)

AC = AC (common)

∠3 = ∠4 ( Given)

So, Δ ABC ≅ Δ ADC {By ASA congruence rule}

HENCE PROVED.
