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 possesses 1 line of symmetry: a vertical line through the apex opposite the base. An equilateral triangle has 3 lines of symmetry, each passing vertically through a vertex. A square exhibits 4 lines of symmetry: horizontal, vertical, and the two diagonals. A circle has an infinite number of lines of symmetry, allowing division into equal parts in countless ways.
