anyone mind helping? i want to sleep Given: BA is congruent to BC prove angle 1 is congruent to angle 3.

Given that BA = BC which shows that ΔABC is isosceles

And, ∠1 Represents BC

and, ∠2 Represents BA

And as BC and BA are equal, we come to know that ∠1 and ∠2 are equal

∠2 = ∠3 because they are opposite angles.

Therefore we can conclude that ∠1 and ∠3 are congruent because ∠1 =∠2 which ∠2 = ∠3 So, ∠1 = ∠3

If my answer helped, please mark me as the brainliest!!

Thank You!

see below

Step-by-step explanation:

since ∠1 ≅ ∠2

opposite angles are equal

therefore, ∠2 ≅ ∠3

cross multiplying, we get :

⇒ (3) × (5) = (9) × (x)

⇒ 15 = 9x

i'm not really sure how to answer that
