A triangle. -wrong #no it is not a triangle it would be correct if they were asking for sides this is rotational symetry
An isosceles triangle has one line of symmetry
Every right circular cone, conic section, and regular polygon has at least one line of symmetry.
a line
i dont think any1 knows * * * * * A concave polygon has at least one reflex angle. Equivalently, in a convex polygon, a line joining ANY two points in (or on) the polygon lie wholly within (or on) the polygon. In a concave polygon there are at least two points for which the line joining them does not lie wholly inside (or on) the polygon.
For example an isosceles triangle has only one line of symmetry
here's one shape,issoleces triangle.(p.s hope i spelt it right!)
1
Pentagon
triangle
A triangle. -wrong #no it is not a triangle it would be correct if they were asking for sides this is rotational symetry
square, rectangle, circle, parallelogram, trapezoid, oval/ellipse, many others all wrong dont read it
yes it has millions it can have a line of symetry from any angle
Most common shapes have a line of symmetry. For example, if you fold a heart in half, both sides will match up. Shapes like Squares, equilateral triangles, and circles have even more.
a shape with a line of symmetry
square
The 2D shape which has one line of symmetry is the trapezium.
