Any isosceles triangle that is not also equilateral has exactly one line of symmetry.
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 normally but if it is a right angle isosceles triangle it will have 1 line of symmetry
It depends. If it is a right isosceles triangle, it has one axis of symmetry (the line which would bisect the right angle). A right scalene triangle has no axis of symmetry.
An isosceles triangle has 1 vertical line of symmetry
One.One.One.One.
An isosceles triangle has only 1 line of symmetry.
An Isosceles triangle has at least one line of symmetry but if it has more than one line of symmetry it can be an Equilateral triangle as well as a Isosceles Triangle. So a triangle with one line of symmetry is always Isosceles and If it has more than one it is always an Equilateral triangle as well as an Isosceles triangle. Example of an Isosceles triangle:
An isosceles triangle has two equal sides and one line of symmetry
An isosceles triangle has two sides and angles that are equal, causing it to have exactly a line of symmetry through it. A right triangle has one angle that is 90 degrees. An isosceles right triangle will always have one angle that is 90 degrees, while the other two angles will be 45 degrees.
ohcourse an isosceles triangle has a line symmetry
An isoceles triangle does not have rotation symmetry
