Points a(-2, 4), b(1, 3), c(4, -1) and d form a parallelogram. what are the coordinates of d?

What is the measure of angle tvu shown in the diagram below

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

Wich statement could be used to explain why the function h(x)= x^3 has an inverse relation that is also a function
