Answer 1

Answer:

I)

segment ab is congruent to segment ad (given)

segment cb is congruent to segment cd (given)

segment ac is congruent to segment cs (common arm)

Therefore,

∆abc is congruent to ∆adc (by sss test)

II)

we know that ∆abc and ∆adc are congruent.

therefore,

angle b is congruent to angle d (cact)
