PLZ HELP IF U CAN I KNOW THE ANSWER BUT SOMEONE JUST NEED TO CHECK IT !
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.

Answer 1

The ratio of their corresponding sides is 1:2? is that right C?

Answer 5

@Directrix can u tell me if i am correct or not?

Answer 6

If you use the distance between two points calculator at
http://easycalculation.com/analytical/distance.php ,

it appears that corresponding sides of the quadrialterals are congruent..

Answer 7

That would rule out these two options:

The ratio of their corresponding angles is 1:2.

The ratio of their corresponding sides is 1:2

---
Are they supposed to be the same or is that a typo?

Answer 8

no they are same

Answer 9

I see now. One is sides and the other is angles. Sorry.

Answer 10

I agree with you that A is the only viable option left.

Answer 11

k thank you so it is A :)

Answer 12

Learn to find the distance between points or use that online calculator. That will speed up your work.

Answer 13

k thanks for ur help and i will use distance formula! and all thanks
