It can be but it doesn't have to be. Some triangles are symmetrical and others aren't.
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.
Yes it has 3
Because if you rotate it about its center it looks different (not symmetric) no matter what the angle is.
a circle is symmetric so is a triangle, a rectangle.
Some triangles are symmetric, while others are not. All equilateral and isosceles triangles are symmetric.all triangles are symmetric.

All the sides of a triangle is symmetrical.

When in a triangle, for angle A, B, C; As the symmetric property of congruence , when ∠A ≌ ∠B then ∠B ≌ ∠A and when ∠A ≌ ∠C then ∠C ≌ ∠A and when ∠C ≌ ∠B then ∠B ≌ ∠C This is the definition of symmetric property of congruence.

The number of lines of symmetry of a triangle depends on what triangle you are talking about. An equilateral triangle has three lines of symmetry (one corresponding to each altitude). An isosceles triangle (that is not equilateral) has one line of symmetry. Other triangles have none.
