An isosceles triangle.
An isosceles triangle has one line of symmetry. This line runs vertically through the apex (the top vertex) and bisects the base, dividing the triangle into two congruent halves. The two equal sides reflect across this line, demonstrating the symmetry.
It has 1 line 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,
A triangle has 3 sides and if two sides are equal then it's an isosceles triangle with one line if symmetry but if all sides are equal then it's an equilateral with three lines of symmetry.
It depends on what kind of triangle. A scalene triangle (no equal sides or angles) would not have any lines of symmetry. An isosceles triangle would have 1 line of symmetry, and an equilateral triangle would have 3 lines of symmetry.
2 congruent sides and the opposite angles of the sides are also congruent. There is only 1 line of symmetry.
An isosceles triangle has one line of symmetry. This line runs vertically through the apex (the top vertex) and bisects the base, dividing the triangle into two congruent halves. The two equal sides reflect across this line, demonstrating the symmetry.
It has 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.
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,
A triangle has 3 sides and if two sides are equal then it's an isosceles triangle with one line if symmetry but if all sides are equal then it's an equilateral with three lines of symmetry.
An isosceles trapezium.
It depends on what kind of triangle. A scalene triangle (no equal sides or angles) would not have any lines of symmetry. An isosceles triangle would have 1 line of symmetry, and an equilateral triangle would have 3 lines of symmetry.
the only way for a right triangle to have a line of symmetry, is if the legs of the triangle are congruent. Or you can show that both non-right angles are congruent (45 degrees). you may also prove that the altitude of the triangle bisects the hypotenuse or that it equals 1/2 of the hypotenuse.
An ISOSCELES TRiangle. The line of symmetry is from the angle of the two equal adjacent sides, to the mid-point of the NON-equal side.
An isosceles triangle has two equal sides and one line of symmetry
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.
