1 line of symmetry.
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.
yes * * * * * Usually, no. Only isosceles right angled triangles have a line of symmetry.
No such thing as a regular triangle. You need to be more accurate in your triangular description. Equilateral triangle is symmetric about three lines of symmetry. Isosceles triangle is symmetric one line of symmetry. Right-angled, and Scalene triangles have no lines of symmetry.
It has 1 line of symmetry
Right-angled triangles can be symmetrical, but only under specific conditions. An isosceles right-angled triangle, where the two legs are of equal length, exhibits symmetry along the line that bisects the right angle. However, a scalene right-angled triangle, with all sides of different lengths, lacks any line of symmetry. Therefore, while some right-angled triangles are symmetrical, many are not.
it has only one line of symmetry.

Right triangles can have only one line of symmetry. Only right triangles with two 45 degree angles can have a line of symmetry.
A scalene triangle that is not right angled.
None normally but if it is a right angle isosceles triangle it will have 1 line of symmetry
