Answer 1

Step-by-step explanation:

in triangle ABC and ADC ,

i)AC =AC(common)

ii)AB=AD(given)

iii)BC=DC(given)

hence, triangles ABC is congruent to triangle ADC by SIDE SIDE SIDE rule of congruency.

2) in triangle AOB and AOD

i)AB= AD(GIVEN)

ii)AO=AO(COMMON)

iii)ANGLE AOB = AOD (EACH 90°)

HENCE TRIANGLE AOB IS CONGRUENT TO TRIANGLE AOD BY SIDE SIDE ANGLE RULE OF CONGRUENCY.

3) BO=DO ( BY CPCT)
