Answer 10

First thing is to draw the figures.
We have a triangle ABC where AB does not equal BC.
BD is the median splitting AC in two equal parts


If BD were perpendicular to AC then angle BDC and angle BDA would be right angles.
If they were right angles then BD^2+CD^2 would equal BC^2
and AD^2+BD^2 would equal AB^2
and since BD=BD and AD=DC then BC and BA would be equal but we are told that AB is not congruent to BC therefore they can't be right triangles and therefore angle BDC and angle BDA are not right angles.
Since they are not right angles, the lines(segment) BD and AC are not perpendicular. QED

google it

Answer 14

do ask your teacher or tutor

Answer 15

my teacher

Answer 16

I'll search it when I go home

Answer 17

SAS. The line in the middle is congruent to itself, then corresponding right angles, and if it's in the middle, then it splits the bottom in half, making both part congruent as well.

Answer 18

SAS and I agree with danniinotcool
