Answer:
Hii
Step-by-step explanation:
an equilateral Triangle
=> ∠ A = ∠B = ∠C = 60°
AB = BC = CA
BC is produced to D such that BC=CD
=> CA = CD
=> ∠CAD = ∠CDA
∠C = ∠ACD = ∠CAD + ∠CDA ( Sum of Exterior angle of a triangle = Sum of opposite two angles of triangle)
=> 60° = 2 ∠CAD
=> ∠CAD = 30°
∠BAD = ∠BAC + ∠CAD
=> ∠BAD = 60° + 30°
=> ∠BAD = 90°
=> DA ⊥ AB
