Question

In complex plane the points $$1 + 3i, 5 + i, 3 + 2i$$  are


A
Vertices of a right angled triangle
loader
B
Collinear

C
Vertices of an equilateral triangle

D
Vertices of an obtuse angled triangle

Solution

The correct option is B Collinear
Let the three points be $$A(1,3)$$ , $$B(5,1)$$ and $$C (3,2)$$. 

$$AB = \sqrt{16+4} =2\sqrt 5$$

$$AC =\sqrt {4+1} =\sqrt 5$$

$$BC = \sqrt{4+1} =\sqrt 5 $$

$$AB = AC+BC$$

Hence, option B is correct
