Answer with explanation:
Proof Provided by Adam for vertical angles to be equal:
The Sum of Angles in Complete Circle is 180°.
So,∠1 + ∠2 +∠3+∠4=360°
∠2+∠3=180°------[t is a straight line]
∠1 + 180°+∠4=360°
∠1+∠4=360° -180°
Also, ∠1 +∠4=180°
But, Here it is given that,
∠1 = ∠ 3
⇒Incorrect proof Done by Adam
⇒Proof Provided by Darius for vertical angles to be equal:
∠1 + ∠4=180°------(t is a straight line)-----(1)
Also, ∠1 + ∠2=180°------(P Q is a straight line)-----(2)
From (1) and (2)
⇒∠1 + ∠4=∠1 + ∠2→→→(Transitive Property of Equality)
⇒ ∠4=∠2→→→(Subtraction Property of Equality)
Correct Proof done by Darius
