1. Properties of Parallelograms 2 pairs of opposite sides parallel

2. Properties Opposite angles are congruent Consecutive Angles Supplementary Opposite sides Congruent Diagonals bisect each other Could you prove all of these properties with just using opposite sides parallel

3. Proof SR ABCD is a parallelogramG AC = ACReflexive <BCA=<CADAI <BAC=<ACDAI ABC=CDAASA Sides =CPCTC Angles=CPCTC Diagonals Bisect each other use bowtie triangles and property of opposite sides congruent Consecutive angles supplementary is SSI
