Determine if triangle RST with coordinates R (3, 4), S (5, 5), and T (6, 1) is a right triangle. Use evidence to support your claim. If it is not a right triangle, what changes can be made to make it a right triangle? Be specific.

find the length of each side of the triangle, either by graphing or using the distance formula then determine whether the triangle satisfies the Pythagorean theorem

i figured out that the triangle is not a right angle

Looking at the figure, do any of the angles look close to 90 degrees? maybe
anonymous
  • anonymous
no
anonymous
  • anonymous
it is not 90ยบ
phi
  • phi
did you find the slopes ?
anonymous
  • anonymous
yes
phi
  • phi
what did you get ?
anonymous
  • anonymous
R (3,4) and S (5,5) S (5,5) and T (6,1) R (3,4) and T (6,1)
phi
  • phi
what is the slope between points R and S ?
anonymous
  • anonymous
1/2
phi
  • phi
yes, and the slope from R to T is -1 so the lines do not form a right angle (if we got -2 slope from R to T it would be a right angle)
phi
  • phi
to find a point that forms a right triangle, we could adjust point S so the slope from R to S is +1 (the "negative reciprocal" of -1 is - 1/(-1) = -1/-1 = 1 )
phi
  • phi
for example, if we move S from (5,5) to (4,5) the slope from R to S' will be 1 (if you work it out)

or you could move point S from (5,5) to (5,6)
anonymous
  • anonymous
which way is easier?
phi
  • phi
it's the same work either way. But they ask the question If it is not a right triangle, what changes can be made to make it a right triangle? so you should pick one way and show it makes a right angle (by showing the slopes are negative reciprocals)
anonymous
  • anonymous
but it doesn't make a right triangle
phi
  • phi
yes, but what changes can be made to make it a right triangle?
anonymous
  • anonymous
oh i stuck on this part
phi
  • phi
you are done with the first part. The slope from R to S is 1/2 the slope from R to T is -1 1/2 is not the negative reciprocal, so the lines do not form a 90 degree angle.

This is what I have!

ok, that looks good. be sure to also find the slope from R to T
