Question

i need help will give medal and fan

The vertices of a quadrilateral ABCD are A(4, 8), B(10, 10), C(10, 4), and D(4, 4). The vertices of another quadrilateral EFCD are E(4, 0), F(10, -2), C(10, 4), and D(4, 4). Which conclusion is true about the quadrilaterals?

The measure of their corresponding angles is equal.

The ratio of their corresponding angles is 1:2.

The ratio of their corresponding sides is 1:2

The size of the quadrilaterals is different but shape is same.

the calculated lengths of sides for each set matches each other
therefore they are congruent.

Answer 6

sorry for the confusion...
when you find the distance between all the points,
compared to the distance between all the points in the other quadrilateral,
they come out to be exactly equal to each other.
therefore their sides and shape is the same.
