Given : AD ⊥ BC
2DB = 3CD
Step-by-step explanation:
ANSWER
AD=AC ( Given )
So, ∠ACD=∠ADC [ Angles opposite to equal sides are equal ]
Now ∠ACD is exterior angle of △ABD
∠ADC=∠ABD+∠BAD [ exterior angles sum of interior opposite angles ]
So, ∠ADC>∠ABD
∠ACD>∠ABD ( from (1))
AB>AC [ side opposite to greater angle is longer ]
∴AB>AD ( As AC=AD given )
Hence, proved.Answer:
