Slope QR = -1/2
Slope RP = 2
the lines QR and RP are perpendicular, PQR is a right triangle
\(QR=\sqrt{5}\)
\(RP=\sqrt{45}\)
\(Area of triangle PQR =(\sqrt{5}*\sqrt{45})/2=15/2\)
Distance PQ is not equal to distance QR or PR
Answer A,B

When 2 lines are perpendicular, so that makes it a right triangle?
