Statement - 1 : If P (cosα, sinα) , Q (cosβ, sinβ) , R (cosγ, sinγ) are vertices of triangle whose orthocentre is (0, 0) then cos (α - β) + cos (β - γ) + cos (γ - α) = -3/2 Statement 2 : In equilateral triangle, orthocenter, circum centre and centroid willcoincide

Correct Answer is : Statement-I is true, statement-2 is true and statement-2 is correct explanation forstatement-I

Statement-I is true, statement-2 is true and statement-2 is correct explanation forstatement-I

Statement-I is true, statement-2 is true and statement-2. is NOT the correctexplanation for statement-I

Statement-I is true, statement-2 is false

Statement-I is false, statement-2 is true
