According to the given information, segment AB is parallel to segment DC and segment BC is parallel to segment AD. Construct diagonal A C with a straightedge. _____________. Angles BAC and DCA are congruent by the Alternate Interior Angles Theorem. Angles BCA and DAC are congruent by the same theorem. Triangles BCA and DAC are congruent according to the Angle-Side-Angle (ASA) Theorem. By CPCTC, opposite sides AB and CD, as well as sides BC and DA, are congruent.

OpenStudy (cheeser5):

Angles BAC and DCA are congruent by the Same-Side Interior Angles Theorem. Diagonal BD is congruent to itself by the Reflexive Property of Equality Diagonal AC is congruent to itself by the Reflexive Property of Equality. Angles ABC and CDA are congruent according to a property of parallelograms (opposite angles congruent)

That's a big no go Houston~ Slenderman2k16

SsameE

OpenStudy (slenderman):

sorry bro

OpenStudy (cheeser5):

its geometry idknothing about geometry neither

OpenStudy (_citrus_):

Sorry idk maybe ask one of the idk more mathy people right now

OpenStudy (anthonyym):

So what's the question

OpenStudy (cheeser5):

Which sentence accuratley completes the proof?

OpenStudy (cheeser5):

@anthonyym

OpenStudy (anthonyym):

Ok I'll try to draw the info they gave

OpenStudy (anthonyym):

Triangles BCA and DAC are congruent according to the Angle-Side-Angle (ASA) Theorem. So you need an angle, angle and side. From the info you have two congruent angles, so you are missing a side.
