Answer:
hey mate :-
Step-by-step explanation:
Given
Quadrilateral's each side is extended
i.e, => AB = AD
To prove
That ABCD is a kite
proof ~ ∠BAD=110°
∠C=20°
∴∠BCD=20°(Vertically opposite angles).
∠CDA=180°-65°=115°
∠B=360-(∠A+∠D+∠C)
∠B=115°
Now in ΔACD and ΔACB
AC=AC (common)
AD=AB(given)
∠CDA=∠CBA(equal)
ΔACD≅ΔACB
CD=CB
AD=AB(adjacent sides are equal)
∠D=∠B(A pair of opposite angles equal)
∴ABCD is a kite .
