PLZ HELP?!?! I WANNA CHECK MY ANSWERS ONLY PLS HELP 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
