here ia a question that was given to me
anonymous
  • anonymous
Well to start off an angle bisector is a line that bisects, or separates into two equal parts, a vertex angle of a triangle.
anonymous
  • anonymous
so am i just drawing a line down the triangle starting at point T|dw:1446683056466:dw|
anonymous
  • anonymous
like that?
anonymous
  • anonymous
Pretty much. Just make sure the two angles the line makes in the triangle are congruent.
anonymous
  • anonymous
ok. thanks can you help me with one other problem
anonymous
  • anonymous
Sure.

i have no idea how to do this
anonymous

\[slope=(y _{2}-y _{1)\div}(x _{2}-x _{1} )\]
anonymous
  • anonymous
that did not work too well...
anonymous
  • anonymous
But basically it is 4-(-9) ------ 2-(-2)
anonymous
  • anonymous
so 4+9 ----- 2+2
anonymous
  • anonymous
or 13/4
anonymous
  • anonymous
how come you would add if it was a neg 9 before
anonymous
  • anonymous
you are subtracting a negative number from a positive which turns the sign into a plus
anonymous
  • anonymous
so 4-(-9) is technically equal to 4+9
anonymous
  • anonymous
ohh ok that makes sense
anonymous
  • anonymous
Two lines that are parallel have the same slope
anonymous
  • anonymous
ok.
anonymous
  • anonymous
Then the slope of a perpendicular line is the negative reciprocal of the original slope.
anonymous
  • anonymous
ohh ok i get it now.
anonymous
  • anonymous
Glad I could help :)
anonymous
  • anonymous
well that is all that i need help with rightness. thank you so much for the help.
anonymous
  • anonymous
*right now
anonymous
  • anonymous
