Answer

No

Work Step by Step

Slope of PQ: $m=(3--1)/(4-2)$ $m = 4/2 = 2$ Slope of QR: $m=(1--1)/(0-2)$ $m=2/-2$ $m = -1$ Slope of PR: $m = (3-1)/(4-0)$ $m = 2/4$ $m = 1/2$ $2 * 1/2 = 1$ $2 * -1 = -2$ $-1 * 1/2 = -1/2$ None of the three pairs of lines have slope products of -1, so the triangle made is not a right triangle.
