What is the Answer (Easy)
Could you give a small explanation too.

Figure abcd is a parallelogram. if point c lies on the line x = 2, what is the y-value of point c

Which term best describes the association between variables a and b

In the following diagram it is given that dec,ab || dc, ad || eb, and ad is congruent to bc. a)why isn't abc a parallelogram even though it has a pair of parallel sides and a pair of congruent sides b)explain why be must be congruent to bc. further explain what type of triangle this makes triangle abc and what it tells you about angle 1 and angle 2c) finally why must angle 3 be congruent to angle 1? further, explain why we know that angle 3 is congruent to angle 2
