An equilateral triangle has three lines of symmetry. Pick a corner, and draw a line from there to the center of the opposite side of the triangle. That is one of the lines of symmetry. You can get the other two lines by doing this to the other two corners. An isosceles triangle only has one line of symmetry and a scalene triangle has none.

There are three lines, three angles, and three sides or a triangle. Each angle of the equilateral triangle is exactly 60 degrees, because each angle is equal.

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.

An equilateral triangle has 3 lines of symmetry whereas an isosceles triangle has 1 line of symmetry but normally no triangles have 2 lines of symmetry.

An equilateral triangle contains at least 2 lines of symmetry (it actually contains 3 lines of symmetry). An equilateral triangle is also radially symmetric.If the question is "Is there a triangle with exactly 2 lines lines of symmetry?", the answer is no.

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 90Â°. 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 90Â° angle.No triangle can have exactly 2 lines of symmetry.

None normally but if it is a right angle isosceles triangle it will have 1 line of symmetry

Assuming that you are talking about an equilateral triangle, it has three lines of symmetry. They bisect each angle.

A right scalene triangle

that depends on the triangle. if the triangle has no two sides that are the same length, then it is called a scalene triangle and it has no lines of symmetry. if the triangle has two sides that are the same length, the triangle has one line of symmetry, starting at the angle where the two same length sides meet, and ending at the center of the opposite side. if all three sides are the same length, the triangle has three lines of symmetry, between any angle an the center of the opposite side.

Any isosceles triangle that is not also equilateral has exactly one line of symmetry.
