An isosceles triangle definitely has three axes of symmetry
perpendicular through any vertex. so there are three axes of symmetry.
A triangle, in general has none. An isosceles triangle has 1 axis of symmetry while an equilateral triangle has 3 axes.
threethere are 3 axes of semmetry in a equilateeral triangle
One, except in the special case where the triangle is also equilateral (in which case, three).
3
Normally, none.
In a regual shape the number of axes of symmetry is equal to number of sides.

One

It is a median.
