Question

solve this full...... plz​

Answer 1

Answer:

In angle ABD & ACD

AB = AC (given)

BD= CD (given)

BC = BC (common)

Therefore, angle ABD & ACD are equal by SSS congruency.

Answer 2

we need to do construction

join AD than,

in ∆ABD and ∆ACD

(1) AB = AC {given}

(2) BD = CD {given}

(3) AD = AD {common}

AAA coungrence ∆ABD=~∆ACD

then by CPCT <ABD = <ACD
