    Assertion [A] All regular polygons of the same number of sides such as equilateral triangle, squares etc. are similar.
    Reason [R] Two polygons are said to be similar, if their corresponding angles are equal and lengths of corresponding sides are proportional.

    A) A is true, R is true; R is a correct explanation for A.

    B) A is true, R is true; R is not a correct explanation for A.

    C) A is true; R is False.

    D) A is false; R is true.

    Correct Answer: A

    Solution :

    Two polygons are similar, if their corresponding angles are equal and sides are proportional.
    \[\because \] In equilateral triangle and square, each angle are equal and sides are also equal therefore, regular polygons are similar.
    Statement I is True and Statement II is True and Statement II is the correct explanation of Statement I.
