please answer this question ​

Answer 1

ANGLE BCD= ANGLE CBA(ALTERNATE INTEROR ANGLR

angle cBD= ANGLE BCA( AIA )

ANGLE CDB = ANGLE BAC( IF TWO SIDE OF THE TRIANGLE IS EQUAL THEN OTHER SIDE IS ALSO EQUAL

SO TRIANGLE ABC CONGURENT TO TRIANGLE DCB

2/ AC= DC ( IF THE INTEROR ANGLE OF TWO TRIANGLES ARE EQUAL THE THE OPPOSITE PARALLEL LINE ARE EQUAL
