Give an example of a figure that has a line of symmetry but does not have rotational symmetry.
Open in App
Solution
The line of symmetry of an isosceles triangle is the angle bisector of its vertical angle, which is in-between the equal sides. However, it does not have any rotational symmetry.
As the dotted line divides the given figure into two equal parts.
So, the dotted line is the line of symmetry for the given isosceles triangle.
