Given:-
BC= 15cm
To Find:-
i) Measurement of AB and AC
ii) Measurement of CD and AD, if tan(∠ADC)=1
To Prove:-
Solution:-
In ΔABC,
Now,
Now,
━━━━━━━━━━━━━━━━━━━━━
Now, In ΔACD
tan(∠ADC)=1
That means,
∠ADC= 45°
Or
D= 45°
So,
Now,
━━━━━━━━━━━━━━━━━━━━━
Now, we know that,
So, by using above properties
