Question

Observe the following figure:​

Answer 1

Solution....

1. In ∆ABC & ∆DBC

=>BC=BC (Common)

=> ang. ABC = ang. DBC { GIVEN IN FIGURE}

=> ang.ACB = ang.DBC { GIVEN IN FIGURE}

.

. . ∆ABC is congruent to ∆DBC by ASA criteria (ANGLE SIDE ANGLE )

2. YES , BOTH THE TRIANGLES ARE CONGRUENT TO EACH OTHER ,, HENCE WE PROVED IN FIRST QUESTIONS.

3. AB = DC (CPCT)

4. AC = DB {CPCT}

HENCE ,, I ANSWERED ALL ...
