Triangle RST has vertices located at R (2, 3), S (4, 4), and T (5, 0).

Part A: Find the length of each side of the triangle. Show your work. (4 points)

Part B: Find the slope of each side of the triangle. Show your work

This is six calculations....3 for slopes between points and three for distances...I'll do ONE of each and you try the rest

 

points 2,3    and   4,4    slope = (y1-y2)/(x1-x2) = (3-4)/(2-4) = 1/2 

  distance    d2 = (x1-x2)^2 + (y1-y2)2 = (2-4)^2 + (3-4)^2 = 4+1 = 5     d^2 =5   d = sqrt 5

 

Now you do the others   slope between points  2 and 3    and 3 and 1   and distances.....
