In △abc, the coordinates of vertices a and b are a(1,−1) and b(3,2). for each of the given coordinates of vertex c, is △abc a right triangle? select right triangle or not a right triangle for each set of coordinates. c(0,2) right triangle or not a right triangle? c(3,-1) right triangle or not a right triangle? c(0,4) right triangle or not a right triangle?

C(0,2) - Not A Right Angle

C(3,-1) - Right Angle

C(0,4) - Right Angle

I took the unit test and after this was the correct and answer. Hope this helps :))

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
