Plz i wanna check my answers only pls check if they are correct? ! in △abc, the coordinates of vertices a and b are a(1,2) and b(−3,−1). 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. right triangle not a right triangle. these are the c vertices and i think that two of them are right triangles. c(−3,−2) not c(0,−5) right triangle c(1,−2) right triangle
