Determine if triangle RST with coordinates R (2, 3), S (4, 4), and T (5, 0) 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.

    check the slopes for the 3 segments see if one of them has a "negative reciprocal" slope of another that is, if say of RS segment gives you a slope of 1/2 and then ST gives you a slope of negative -1/2 reciprocal -2/1 then ST is perpendicular to RS and thus they make up a right-angle and thus a right-triangle

    check the slopes of all 3 segments making up the triangle, for RS, ST and TR

    it does make a right angle. it just shifted by one. Side ST was sifted to the right that is why T is on (0,5) and SR was shifted down by one also which is why R is (2,3) so it still makes a right triangle

    Ok so the slopes are, 1/2, -4, and -1!

    yeah..... so I guess is not a right-triangle then :)

    well.. dunno if it's an isosceles.... looks like it's, but you'd need to check the lengths for the segments by using the distance formula notice that the slopes you've got, do not provide a corresponding negative-reciprocal.... so is not a right-triangle did you get the "negative reciprocal" part?
