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? (5 points)A.The measure of their corresponding angles is equal.
B.The ratio of their corresponding angles is 1:2.
C.The ratio of their corresponding sides is 1:2
D.The size of the quadrilaterals is different but shape is same.

Answers

ABCD are A(4, 8), B(10, 10), C(10, 4), and D(4, 4).
EFCD are E(4, 0), F(10, -2), C(10, 4), and D(4, 4). 

After plotting the points, the conclusion that is true about the quadrilaterals is "A.The measure of their corresponding angles is equal." ABCD is just a reflection of EFCD.

Answer:

A.The measure of their corresponding angles is equal.

10 + x (1x) = 15
-10                -10
----------------------
x = 5

cost= 25 (10 + 15)
