Question

Which one of the following options has the correct sequence of objects arranged in the increasing number of mirror lines (lines of symmetry)?

• A. Circle; Square; Equilateral triangle; Isosceles triangle
• B. Isosceles triangle; Equilateral triangle; Square; Circle
• C. Equilateral triangle; Isosceles triangle; Square; Circle
• D. Isosceles triangle; Square; Equilateral triangle; Circle

Hint:

For symmetry questions, focus on the geometric properties of each figure, such as the number of equal parts or axes of symmetry.

Answer 1

The Correct Option is B

An isosceles triangle has 1 line of symmetry (a vertical line passing through the vertex opposite the base).
An equilateral triangle has 3 lines of symmetry (vertical axis passing through each vertex).
A square has 4 lines of symmetry (horizontal, vertical, and two diagonals).
A circle has infinite lines of symmetry (can be divided into equal parts in many ways).
