Answer 1

I solved this already and got RS=3/4 ST=-3/4 RT=6 but I don't know what makes this a right triangle. Maybe D? I'm not sure...

Answer 4

In order to be a right triangle 2 of the sides must be perpendicular
In other words when u multiply their slope you Must get -1 for the sides to be perpendicular.
RS slope is 1.5
RT slope is zero
ST slope is - 0.75
You see non of those sides when multipleD wouod result -1
Therefore they don't form a perpendicular lines. And when perpendicular lines aren't formed then the result is there won't be a 90 degrees angle which means the triangle wouldn't be right triangle
