Geometry definitions needed to solve proofs about Parallelograms

Quiz yourself by thinking what should be in each of the black spaces below before clicking on it to display the answer.
        Help!  

Question
Answer
parallelgram   If a quadrilateral with both pairs of opposite sides // then parallelograme  
🗑
trapezoid   If a quadrilateral with exactly one side pair of opposite sides // then trapezoid  
🗑
Distance Between // Lines   Is the length of the prependicular segment from a point on line1 and line 2.  
🗑
If 2 lines are //   then they are equdistant every where  
🗑
If a quadrilateral is a parallelgram then   both pairs of opposite sides are //  
🗑
If a quad. is a para llelagram then   both pairs of opposite side are conguent  
🗑
If a quad. is a parallelgram then   both pairs of opposite angles are congruent.  
🗑
If quad. is a parallelgram then   consecutive angles are supplementary  
🗑
If a quad. is a parallelgram then   diagonals bisect each other  
🗑
If both pairs of opposite sides of a quad are //   then parallelogram  
🗑
If both pairs of opposite sides of a quad. are congruent   then parallelogram  
🗑
If one pair of opposite sides of a quad are both congruent and //   then parallelogram  
🗑
If both pairs of opposite angles of a quad. are congrunt   then parallelogram  
🗑
If the diagonals of quad. bisects each other   then paralleogram  
🗑
If 3 or more // lines intecpt congrunt segments on one transversal then   intersect congrunt on every transversal.  
🗑


   

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
