Indicate the equation of the line that is the perpendicular bisector of the segment with endpoints (4, 1) and (2, -5).
balandron [24]
If it is bisector then it co ordinate points is in mid way(3,-2)

and it is perpendicular so its slope m2=-1/m1
where m1 is slope of another line passes through (4,1) nd (2,-5)

m1=-5-1/2-4=3
m2==-1/3

so equation of line is
y-3= -1/3(x+2)

Answer:

See Explanation

Step-by-step explanation:

Given

\triangle ABC = \triangle DE F

Required

Which would not prove the similarity

\triangle ABC = \triangle DE F  implies that:

The following angles are congruent

\angle A = \angle D

\angle B =\angle E

\angle C =\angle F

And the following lengths are congruent

AB = DE

BC =EF

CA = FD

The options are not clear; so, it's a bit difficult to select the correct option.

<em>Any of the options that is different from the above list of 6 congruent pairs is the answer to your question.</em>
