yes
An equilateral triangle and an isoceles triangle have one 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:
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 two equal sides and one line 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.
No a equilateral triangle does not have one line of symmetry.It has 3. My 5Th grade teacher told me
None. A isosceles triangle has one line of symmetry and a equilateral triangle has three.
Many shapes have more than one line of symmetry. These include a rectangle, equilateral triangle, and a square. While a rectangle has two lines of symmetry, an equilateral triangle has three.
None. An isosceles triangle has only one line of symmetry, while an equilateral triangle has three.
#1~ One VERTICAL line straight in the middle of the 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.
YES!!! An equilateral triangle has three lines of symmetry. They are drawn from any one corner to the opposite base. They should all intersect at the centre of the triangle. By comparison, an Isosceles triangle has only one line of symmetry. From the one unequal angle to the opposite side. Right angled, and scalene triangles do not have lines of symmetry.
