Question

plz solve this sum of congruence

From the adjoining figure prove that
1. angle b is equal to angle d
2. ab is parallel to dc​

Answer 1

Answer:

I can't solve it sorry

Answer 2

In Triangle ADC and Triangle ABC:

AB=CD (GIVEN)

BC=AD (GIVEN)

AC=AC (COMMON)

Therefore, Triangle ADC ~= Triangle ABC

LB= LD (CPCT)

also, LACD =LCAB (CPCT)

since,LACD=LCAB are alternate angles.

therefore, CD||AB (by alternate angles)
