Which statement explains how you could use coordinate geometry to prove the opposite sides of a quadrilateral are congruent? Use the slope formula to prove the slopes of the opposite sides are the same.
Use the slope formula to prove the slopes of the opposite sides are opposite reciprocals.
Use the distance formula to prove the lengths of the opposite sides are the same.
Use the distance formula to prove the midpoints of the opposite sides are the same.

answer: x

answer: i don't understand. what are the options

step-by-step explanation:

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl

hope this !
