Yes it has three.
An equilateral triangle has both line symmetry and rotational symmetry. A non-equilateral isosceles triangle has line symmetry but not rotational symmetry. A scalene triangle has neither kind of symmetry.
An equilateral triangle and an isoceles triangle have one line of symmetry.
Only an equilateral triangle has rotational symmetry.
An isosceles triangle has 1 line of symmetry, an equilateral triangle has 3 and a scalene triangle has no lines of symmetry.
It will have 3 lines of symmetry if its an equilateral triangle and only 1 line of symmetry if its an isosceles triangle.
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:
yes
If its an isosceles triangle it has 1 line of symmetry but if its an equilateral triangle it has 3 lines of symmetry
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.
YES & NO. YES ; Equilateral triangles , Three lines of symmetry, Iine from each point to the mid point of the opposite line(Base). Isosceles triangles One line of symmetry , from the conjunction of the two equal lines , to the opposite base. NO ; Scalene triangles. Because no lines are of equal length. A Right-Angled Triangle can be isosceles or scalene. Which ever one, then the above rules apply.
An isosceles triangle has two equal sides and one line of symmetry
Yes either an isosceles triangle or an equilateral triangle
