No.
An isosceles triangle has 1 vertical line of symmetry
Not normally but if it's an isosceles trapezoid they are congruent
An isosceles triangle has two equal sides and one line of symmetry
It has 1 line of symmetry.
No.
Only if it is in the form of an isosceles trapezoid
There is only one in a trapazoid because if you look at it there is only one line that can be cut to have both sides equal
None.
In general, none.
An ISOSCELES TRiangle. The line of symmetry is from the angle of the two equal adjacent sides, to the mid-point of the NON-equal side.
None.
An isosceles triangle has 1 vertical line of symmetry
ohcourse an isosceles triangle has a line symmetry
Not normally but if it's an isosceles trapezoid they are congruent
An isosceles triangle has 1 line of symmetry
a trapazoid
