Given:

$(a)$. an isosceles triangle?

$(b)$. a circle?


To do: To write another name that can be given to the line of symmetry of the given shapes.


Solution:

As known that an isosceles triangle has only one line of symmetry and this is the line segment joining a vertex to the midpoint of the opposing side, and bisecting it. So, we can call it a median.

A circle has infinitely many lines of symmetry passing through the center, so we can definitely call it, a diameter.


Thus, the other name that can be given to the line of symmetry of


$(a)$. The Median of an isosceles triangle is another name of its line of symmetry.


$(b)$. Diameter of a circle is  another name of its line of symmetry.
