Solution

Let A (2, 1) B (4, 0), C (3, 3) and D (3, 2) be the given points.Now, slope of AB=0+14+2=16Slope of BC=3034=3Slope of CD=2333=16Slope of DA=122+3=3Clearly, we have,Slope of AB = Slope of CDSlope of BC = Slope of DAAs the slopes of opposite sides are equal.Therefore, both pair of opposite sides are parallel.Hence, the given points are the vertices of a parallelogram.
