Answer:

Step-by-step explanation:

given :abcd is a quadrilateral and ac is diagonal

to proof : abc is congruent to cda and ab is parallel to cda

proof

ac =ac (common side)

angle bac =angle dac ( alternate interior bangles are equal)

angle dac =angle dca ( alternate interior angles are equal)

therefore abc =cda

since abc =cda

ab is parallel to cd by cpct
