slope = rise over run = y/x
A (-1,3) slope = 3/-1 = -3
B (1,2) slope = 2/1 = 2
C (-3,-1) slope = -1/-3 = 1/3
2 lines need to be negative reciprocals in order to be a right triangle
negative reciprocal of -3 is 1/3
so this is a right triangle
Theres no graph but 10x xy
A straight line has an angle of 180 degrees. By perpendicularly cutting it, you are splitting the line into 2. Which means there will be an equal amount of degrees on either side of the line. 180/2=90.
90 degrees on either side of the perpendicular bisector.
sum should be: 5,664 + 816 = 6,480
