The number of lines of symmetry of a triangle depends upon the kind of triangle it is:A scalene triangle with no side lengths equal has no lines of symmetry;An isosceles triangle with two sides equal has 1 line of symmetry that bisects the angle between the two equal sides;An equilateral triangle with all three sides equal has three lines of symmetry - the three lines are the bisectors of the three angles.A right triangle is a triangle where one angle is 90°. A right triangle is either a scalene triangle with no lines of symmetry or an isosceles triangle (where the legs are of equal length) with one line of symmetry which bisects the 90° angle.No triangle can have exactly 2 lines of symmetry.
0 lines of symmetry
a triangle has 0 lines of symmetry.
equilateral triangle
No triangle has two lines of symmetry. A right triangle and an Isoscoles triange each have one line of symmetry, and an equilateral triangle has three.
None normally but if it is a right angle isosceles triangle it will have 1 line of symmetry
A scalene triangle that is not right angled.
For a right isosceles triangle (45-45-90), there is one line of symmetry that bisects the hypotenuse. For all other right triangles, there are zero lines of symmetry.
caca
it has only one line of symmetry.
Not necessarily, except rotational symmetry of order 1.
One.
