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 <SRT (the angle at point R) ... though it does not look quite right. I would find the slope from R to S (change in y divided by change in x) and the slope from R to T if the slopes are "negative reciprocals", then you have a right angle.

    R (3,4) and S (5,5) S (5,5) and T (6,1) R (3,4) and T (6,1)

    what is the slope between points R and S ?

    1/2

  24. 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)

    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 )

    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)

    which way is easier?

    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)

    but it doesn't make a right triangle

    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.
