g If the lines intersect or are parallel, give an equation for the plane which contains both lines. If the lines are skew, find a pair of parallel planes with each plane containing one of the lines (hint: in this case, find a vector perpendicular to both lines).

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
