Problem

Which of the following has the greatest number of line of symmetry?

$\textbf{(A)}\ \text{ Equilateral Triangle}$

$\textbf{(B)}\ \text{Non-square rhombus}$

$\textbf{(C)}\ \text{Non-square rectangle}$

$\textbf{(D)}\ \text{Isosceles Triangle}$

$\textbf{(E)}\ \text{Square}$

Solution

An equilateral triangle has 3 lines of symmetry. A non-square rhombus has 2 lines of symmetry. A non-square rectangle has 2 lines of symmetry. An isosceles trapezoid has 1 line of symmetry. A square has 8 lines of symmetry.


Therefore, the answer is $\boxed{ \textbf{(E)}\ \text{square} }$.
