There are no lines of symmetry.
If you are classifying triangles by their angles, an obtuse triangle has one obtuse angle and two acute angles. A triangle can have at most one obtuse angle. If the two acute angles are congruent, the triangle would also be isosceles.
An ellipse has two lines of mirror symmetry: the line that includes the two foci of the ellipse and the perpendicular bisector of the segment of that line between the two foci.
None, unless it's also isosceles (1.e. 45 degrees for the other two sides).
An isosceles triangle
If the other two angles are equal then it's an isosceles triangle if they are not equal then it's an obtuse triangle.
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.
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.
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.
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.
An equilateral triangle will have three lines of symmetry. Others will have one (or none). There is no triangle with only two.
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.
If you mean which triangle has at least two lines of symmetry, I can answer your question: an equilateral triangle has three lines of symmetry-- one passing through the center of each side and through the opposite point, perpendicular to the side.
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.
A triangle........I think
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.
An equilateral triangle and an isosceles triangle would both have lines of symmetry that would split it into two triangles.
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.
