Cube roots of unity are the vertices of a/an ......... which is inscribed in a circle of unit radius, with its centre at origin

Options

  1. ARight angled triangle
  2. BEquilateral triangle
  3. CScalene triangle
  4. DIsosceles triangle

Correct answer

B. Equilateral triangle

Step-by-step solution

We have, cube roots of unity (1, , ^2 ) are the vertices of an equilateral triangle, which is inscribed in a circle of unit radius and having centre at origin Hence, option (2) is correct.
