**Make correct statements by filling in the symbols ⊂ or ⊄ in the blank spaces:**

**(i) {2, 3, 4} … {1, 2, 3, 4, 5}**

**(ii) {a, b, c} … {b, c, d}**

**(iii) {x: x is a student of Class XI of your school} … {x: x student of your school}**

**(iv) {x: x is a circle in the plane} … {x: x is a circle in the same plane with radius 1 unit}**

**(v) {x: x is a triangle in a plane}…{x: x is a rectangle in the plane}**

**(vi) {x: x is an equilateral triangle in a plane}… {x: x is a triangle in the same plane}**

**(vii) {x: x is an even natural number} … {x: x is an integer}**

**Answer**

**(i)**All elements of set {2, 3, 4} lies in set {1, 2, 3, 4, 5}.

Hence, {2, 3, 4} ⊂ {1, 2, 3, 4, 5}

**(ii)**Element ‘a’ lies in set {a, b, c} and doesn't lies in set {b, c, d}.

Hence {a, b, c} ⊄ {b, c, d}

**(iii)**All student of class XI lies in his school.

{x: x is a student of class XI of your school}⊂ {x: x is student of your school}

**(iv)**All circle of plane cannot be of radius 1 unit.

Hence, {x: x is a circle in the plane} ⊄ {x: x is a circle in the same plane with radius 1 unit}

**(v)**Triangle and rectangle are two distinct things.

Hence, {x: x is a triangle in a plane} ⊄ {x: x is a rectangle in the plane}

**(vi)**Each equilateral triangle is also a triangle.

Hence, {x: x is an equilateral triangle in a plane}⊂ {x: x in a triangle in the same plane}

**(vii)**All even numbers are integers.

Hence, {x: x is an even natural number} ⊂ {x: x is an integer}
