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 right angle
If you mean what type of triangle has perpendicular lines then it is right angle triangle.
It depends what type of triangle it is. If it is a scalene triangle, ie. a triangle with three different length sides and angles, then it won't have any lines of symmetry. If it's an iscosoles triangle, ie. a triangle with two sides and angles of equal length, it has one line of symmetry, but if it's an equalateral triangle, ie. a triangle with all sides and angles the same, then it has three lines of symmetry.
A line of symmetry for a triangle is a line along which a triangle can be folded so that either side of the line is a mirror image shape of the other.An Isosceles triangle, with two equal sides, has a line of symmetry from the center of the base to its opposing vertex.An equilateral triangle with three equal sides has three lines of symmetry, each from the center of a side to its opposing vertex.Any other triangle type, called a scalene triangle, has no lines of symmetry,
No, it is not a type of triangle as a triangle is defined as a polygon with three sides and three angles and a parallelogram has four sides and four angles.
An equilateral triangle.
What type of triangle?
If you mean what type of triangle has perpendicular lines then it is right angle triangle.
One type of symetry is rotation symetry.
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).
a right triangle
Straight lines.
It depends what type of triangle it is. If it is a scalene triangle, ie. a triangle with three different length sides and angles, then it won't have any lines of symmetry. If it's an iscosoles triangle, ie. a triangle with two sides and angles of equal length, it has one line of symmetry, but if it's an equalateral triangle, ie. a triangle with all sides and angles the same, then it has three lines of symmetry.
An equilateral triangle.
It depends on the type of triangle: -- scalene triangles have three sides of different length, and no lines of symmetry -- isoceles triangles have one line of symmetry that includes the apex -- equilateral triangles have three lines of symmetry, all bisectors through a vertex
That depends on what type of triangle it is because an equilateral triangle has 3 lines of symmetry whereas an isosceles triangle has only 1 line of symmetry and any other triangles have no lines of symmetry.
