Hii please help me with this question
given that PG = QR

P = (a , b+c)
Q = (b , c+a)
R = (c , a+b)

show that a, b, c are parallel

Step-by-step explanation:

The slope of PQ is:

m = [(c + a) − (b + c)] / (b − a)

m = (c + a − b − c) / (b − a)

m = (a − b) / (b − a)

m = -1

The slope of QR is:

m = [(a + b) − (c + a)] / (c − b)

m = (a + b − c − a) / (c − b)

m = (b − c) / (c − b)

m = -1

Both lines have the same slope, and therefore are parallel.
