B) (x, y) → (X, Y - 6) and reflected across y = 0 C) (x, y) → (X, Y - 6) and reflected across x= -1 D) (x, y) → (X - 2, Y) and reflected across x= -1

Find the area of the regular hexagon if a side is 20 cm.

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
