An isosceles triangle and a kite have only one line of symmetry.
A one-dimensional shape is a line. A straight line does not have to have a width, only a length. A curved line has both a linear dimension and an angular width (subtended arc).*A point is said to have zero of three classical dimensions, while it does have a dimension of time.
Using a line of symmetry. For example, some shapes, such as a heart, will have one, while circles have an infinite number. The letter M has only one, right through the the V-shape in the middle.
triangle
Only One Line of SymmetryAn isosceles triangle only has one line of symmetry.
yes, the only one-dimensional shape is a line.
Triangle:)
For example an isosceles triangle has only one line of symmetry
An isosceles triangle and a kite have only one line of symmetry.
square...........................
a triangle only has one line of symmetry
An isosceles triangle.
a shape with a line of symmetry
No shape does. However, a line and/or line segment is "one-sided".
In the Euclidian plane, there is only one shape for a line - irrespective of the number of identified points that it goes through. A line is an undefined geometric term and so the description can only be circular, but it is a straight line, with no width, going on for ever in both direction.
Depending on the triangle, there may be three, one, or none.
The 2D shape which has one line of symmetry is the trapezium.
