B
D
с​

Answer 1

Step-by-step explanation:

In triangle ABD and triangle ACD,

angle ADB=angle ADC( each 90°)

AB=AC(given)

AD=AD (common)

therefore, triangle ABD congruent to triangle ACD (by RHS rule of congruency)

Hence, Proved.

Answer 2

Step-by-step explanation:

in triangle ABD and Triangle ACD

angle D= angle D (90 each)

AB=AC (given)

AD=AD (COMMON)

triangle is congruent by SAS

hence proved
