It depends on the definition used. If you are defining an isosceles triangle as having exactly two sides of equal length, then no. If you define it as having at least two, then yes.

An equilateral triangle has three lines of symmetry, but whether or not that counts as an isosceles triangle depends on the definition used. So, maybe.

How many lines of symmetry does a iscosceles triangle have?

None. A isosceles triangle has one line of symmetry and a equilateral triangle has three.


Can a right triangle have three lines of symmetry?

No. The most it can have is one if it is isosceles.


Triangle with 2 lines of symmetry?

A triangle with two lines of symmetry does not exist. It can have one line of symmetry (an isosceles triangle) or three (an equilateral triangle), but not two.


How many lines of symmetry are in a triangle?

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.


What triangle has only 2 lines of symmetry?

None. An isosceles triangle has only one line of symmetry, while an equilateral triangle has three.


How many reflective symmetry lines does a triangle have?

Depending on the triangle:A scalene triangle has no lines of symmetry.An isosceles triangle has 1 (one) line of symmetry.An equilateral triangle has 3 (three) lines of symmetry.


How many lines of symmetry are there in a triangle?

In an equilateral triangle: 3 In an isosceles triangle: 1 In a scalene triangle: 0


Does a triangle have 3 lines of symertry?

Most triangles don't have any lines of symmetry. An isosceles triangle has one. An equilateral triangle has three.


How can I Draw 2 lines of symmetry on a triangle?

You cannot. An equilateral triangle has 3 lines of symmetry, an isosceles has one and a scalene none. So there is no triangle with two lines of symmetry. Of course, you could draw only two of the three possible lines of symmetry for an equilateral triangle.


Does a triangle have more than 1 line of symmetry?

Depending on the triangle, there can be 0, 1, or three lines of symmetry. A scalene triangle (all sides of different lengths) will have no lines of symmetry, an isosceles triangle (exactly two sides of the same length) will have one line of symmetry, and an equilateral triangle (all three sides of the same length) will have three lines of symmetry.


How many symmetric line has the triangle?

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.


What type of triangle has no lines of symmetry?

A scalene triangle. Though it's usually defined as having three sides of different lengths, this is an equivalent definition: all equilateral triangles have three lines of symmetry, and all isosceles triangles have one (no triangle has two lines of symmetry).
