On the plans for a treehouse, a beam represented by QR has endpoints Q(-6,2) and R (-1,8). A connecting beam represented by ST has endpoints S(-3,6) and T(-8,5). Are the beams perpendicular? Explain. (Hint:Graph the points if needed).

Respuesta :

We have the next graph

QR is the beam in red

ST is the beam in blue

As we can see the beams are not perpendicular because they do not intercept each other and they don't form a 90° angle between each other
