Atranslation is applied to the triangle formed by the points a(−1, 4) , b(−1, 10) , and c(3, 6) . the image is the triangle that has vertices a′(3, 4) , b′(3, 10) , and c′(7, 6) .

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
