Answer 1

The vertices of a quadrilateral ABCD are A(−3, 4), B(−4, 1), C(−7, 2), and D(−7, 6). The vertices of another quadrilateral EFCD are E(−11, 4), F(−10, 1), C(−7, 2), and D(−7, 6). Which conclusion is true about the quadrilaterals?

Their corresponding diagonals are equal.
The measures of their corresponding angles are not identical.
The lengths of their corresponding sides are unequal.
Their shapes and sizes are not identical.

Answer 2

i think its A

Answer 3

Answer 5

work out the distances between the points

for example length of the side AB = sqrt[ (-4--3)^2 + (1 - 4)^2] = sqrt(1 + 9) = sqrt10

length of EF = sqrt(1 + (-3)^20 = sqrt10
so measure of AB = measure of EF

Answer 6

so A

Answer 7

well those are not diagonals
the diagonals are AC and EC , and BD and FD.

Answer 8

check those out

AC = sqrt[ (-7--3)^2 + (2-4)^2] = sqrt( 20)

do the same calculation for EC

Answer 9

if that comes to sqrt20 then those 2 diagonals are equal
